I need to convert a string with hours, minutes, seconds and milliseconds "hh:mm:ss:mil" to the floating-point number that HTML audio player uses for currentTime.
I can't find any conversion algorithm that does this! The closest I've found converts to seconds as integers, while I need something like this
"00:00:38:000" -> 38.0 (NOT 2280)
"01:15:02:773" -> 4502.773
My Code so far - but it's wrong
function time2secs(time) {
// 00:03:30 -> 3.5 seconds
var t = time.split(':');
if (t.length < 4) t[3] = 0; // if a missing millisecs, then set it to 0
var seconds = parseInt(t[0]) * 60 * 60 + parseInt(t[1]) * 60 + parseInt(t[2]) + parseInt(t[3]) / 1000;
return seconds / 60;
}
try this
function timeToSec(time){
var arr=time.split(":");
return parseInt(arr[0])*3600+ parseInt(arr[1])*60+ parseInt(arr[2])+ parseInt(arr[3])*0.1000
}
console.log(timeToSec("00:00:38:000" ))
console.log(timeToSec("01:15:02:773" ))
Does this code work as you expect?
function time2secs(time) {
var t = time.split(':');
if (t.length < 4) t[3] = 0;
let second = (parseInt(t[0]) * 60 * 60) + (parseInt(t[1]) * 60) + parseInt(t[2]) + (parseInt(t[3]) / 1000);
return t[3] == 0 ? second + ".0" : second;
}
This is a common problem but I'm not sure how to solve it. The code below works fine.
var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
However, when I get to 1 hour or 3600 seconds it returns 0 minutes and 0 seconds. How can I avoid this so it returns all the minutes?
To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):
const minutes = Math.floor(time / 60);
And to get the remaining seconds, multiply the full minutes with 60 and subtract from the total seconds:
const seconds = time - minutes * 60;
Now if you also want to get the full hours too, divide the number of total seconds by 3600 (60 minutes/hour · 60 seconds/minute) first, then calculate the remaining seconds:
const hours = Math.floor(time / 3600);
time = time - hours * 3600;
Then you calculate the full minutes and remaining seconds.
Bonus:
Use the following code to pretty-print the time (suggested by Dru):
function str_pad_left(string, pad, length) {
return (new Array(length + 1).join(pad) + string).slice(-length);
}
const finalTime = str_pad_left(minutes, '0', 2) + ':' + str_pad_left(seconds, '0', 2);
Another fancy solution:
function fancyTimeFormat(duration) {
// Hours, minutes and seconds
const hrs = ~~(duration / 3600);
const mins = ~~((duration % 3600) / 60);
const secs = ~~duration % 60;
// Output like "1:01" or "4:03:59" or "123:03:59"
let ret = "";
if (hrs > 0) {
ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
}
ret += "" + mins + ":" + (secs < 10 ? "0" : "");
ret += "" + secs;
return ret;
}
console.log(
fancyTimeFormat(1),
fancyTimeFormat(10),
fancyTimeFormat(100),
fancyTimeFormat(1000),
fancyTimeFormat(10000),
);

For people dropping in hoping for a quick simple and thus short solution to format seconds into M:SS :
function fmtMSS(s){return(s-(s%=60))/60+(9<s?':':':0')+s}
done..
The function accepts either a Number (preferred) or a String (2 conversion 'penalties' which you can halve by prepending + in the function call's argument for s as in: fmtMSS(+strSeconds)), representing positive integer seconds s as argument.
Examples:
fmtMSS( 0 ); // 0:00
fmtMSS( '8'); // 0:08
fmtMSS( 9 ); // 0:09
fmtMSS( '10'); // 0:10
fmtMSS( 59 ); // 0:59
fmtMSS( +'60'); // 1:00
fmtMSS( 69 ); // 1:09
fmtMSS( 3599 ); // 59:59
fmtMSS('3600'); // 60:00
fmtMSS('3661'); // 61:01
fmtMSS( 7425 ); // 123:45
Breakdown:
function fmtMSS(s){ // accepts seconds as Number or String. Returns m:ss
return( s - // take value s and subtract (will try to convert String to Number)
( s %= 60 ) // the new value of s, now holding the remainder of s divided by 60
// (will also try to convert String to Number)
) / 60 + ( // and divide the resulting Number by 60
// (can never result in a fractional value = no need for rounding)
// to which we concatenate a String (converts the Number to String)
// who's reference is chosen by the conditional operator:
9 < s // if seconds is larger than 9
? ':' // then we don't need to prepend a zero
: ':0' // else we do need to prepend a zero
) + s ; // and we add Number s to the string (converting it to String as well)
}
Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).
2020 UPDATE
Using basic math and simple javascript this can be done in just a few lines of code.
EXAMPLE - Convert 7735 seconds to HH:MM:SS.
MATH:
Calculations use:
Math.floor() - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor
The Math.floor() function returns the largest integer less than or equal to a given number.
% arithmetic operator (Remainder) - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder
The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.
Check out code below. Seconds are divided by 3600 to get number of hours and a remainder, which is used to calculate number of minutes and seconds.
HOURS => 7735 / 3600 = 2 remainder 535
MINUTES => 535 / 60 = 8 remainder 55
SECONDS => 55
LEADING ZEROS:
Many answers here use complicated methods to show number of hours, minutes and seconds in a proper way with leading zero - 45, 04 etc. This can be done using padStart(). This works for strings so the number must be converted to string using toString().
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart
The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.
CODE:
function secondsToTime(e){
const h = Math.floor(e / 3600).toString().padStart(2,'0'),
m = Math.floor(e % 3600 / 60).toString().padStart(2,'0'),
s = Math.floor(e % 60).toString().padStart(2,'0');
return h + ':' + m + ':' + s;
//return `${h}:${m}:${s}`;
}
console.log(secondsToTime(7735)); // 02:08:55
/*
secondsToTime(SECONDS) // HH:MM:SS
secondsToTime(8) // 00:00:08
secondsToTime(68) // 00:01:08
secondsToTime(1768) // 00:29:28
secondsToTime(3600) // 01:00:00
secondsToTime(5296) // 01:28:16
secondsToTime(7735) // 02:08:55
secondsToTime(45296) // 12:34:56
secondsToTime(145296) // 40:21:36
secondsToTime(1145296) // 318:08:16
*/
2019 best variant
Format hh:mm:ss
console.log(display(60 * 60 * 2.5 + 25)) // 2.5 hours + 25 seconds
function display (seconds) {
const format = val => `0${Math.floor(val)}`.slice(-2)
const hours = seconds / 3600
const minutes = (seconds % 3600) / 60
return [hours, minutes, seconds % 60].map(format).join(':')
}
You can also use native Date object:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
Of course this solution works only for timeInSeconds less than 24 hours ;)
function secondsToMinutes(time){
return Math.floor(time / 60)+':'+Math.floor(time % 60);
}
To add leading zeros, I would just do:
const secondsToMinSecPadded = time => {
const minutes = "0" + Math.floor(time / 60);
const seconds = "0" + (time - minutes * 60);
return minutes.substr(-2) + ":" + seconds.substr(-2);
};
console.log(secondsToMinSecPadded(241));
Nice and short
Moment.js
If you are using Moment.js then you can use there built in Duration object
const duration = moment.duration(4825, 'seconds');
const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25
Clean one liner using ES6
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
The most concise method I found can be done using in just one line:
let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`
Explanation
`${...}`Template literals. Allows for expressions to be converted into a string from within the string itself.Note: Incompatible with IE.
timeInSeconds/60|0Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)
timeInSeconds%60Remainder (modulo). Gives the remainder of the variable divided by 60.
Hours
This method can be expanded to include hours like this:
let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`
Repeating this process, you can even include days.
A one liner (doesnt work with hours):
function sectostr(time) {
return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
}
Seconds to h:mm:ss
var hours = Math.floor(time / 3600);
time -= hours * 3600;
var minutes = Math.floor(time / 60);
time -= minutes * 60;
var seconds = parseInt(time % 60, 10);
console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));
The Following function will help you to get Days , Hours , Minutes , seconds
toDDHHMMSS(inputSeconds){
const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
let ddhhmmss = '';
if (Days > 0){
ddhhmmss += Days + ' Day ';
}
if (Hour > 0){
ddhhmmss += Hour + ' Hour ';
}
if (Minutes > 0){
ddhhmmss += Minutes + ' Minutes ';
}
if (Seconds > 0){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}
alert( toDDHHMMSS(2000));
After all this, yet another simple solution:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());
Another but much more elegant solution for this is as follows:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* #param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};
function formatSeconds(s: number) {
let minutes = ~~(s / 60);
let seconds = ~~(s % 60);
return minutes + ':' + seconds;
}
For adding zeros I really don't see the need to have a full other function where you can simply use for example
var mins=Math.floor(StrTime/60);
var secs=StrTime-mins * 60;
var hrs=Math.floor(StrTime / 3600);
RoundTime.innerHTML=(hrs>9?hrs:"0"+hrs) + ":" + (mins>9?mins:"0"+mins) + ":" + (secs>9?secs:"0"+secs);
Its why we have conditional statements in the first place.
(condition?if true:if false) so if example seconds is more than 9 than just show seconds else add a string 0 before it.
var seconds = 60;
var measuredTime = new Date(null);
measuredTime.setSeconds(seconds); // specify value of SECONDS
var Time = measuredTime.toISOString().substr(11, 8);
document.getElementById("id1").value = Time;
<div class="form-group">
<label for="course" class="col-md-4">Time</label>
<div class="col-md-8">
<input type="text" class="form-control" id="id1" name="field">Min
</div>
</div>
Try this:
Converting Second to HOURS, MIN and SEC.
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}
1 - Get rest of division using %. Now you have the seconds that don't complete a minute
2 - Subtract the seconds obtained in step 1 from the total. Now you have the minutes
For example, let's assume you have 700 seconds:
seconds = 700%60); //40 seconds
minutes = (700 - (700%60))/60; //11
//11:40
I was thinking of a faster way to get this done and this is what i came up with
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
If we want to convert "time" to minutes and seconds, for example:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
Put my two cents in :
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
So this :
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
Will have the following output :
[1,41];
Then you can print it like so :
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
export function TrainingTime(props) {
const {train_time } = props;
const hours = Math.floor(train_time/3600);
const minutes = Math.floor((train_time-hours * 3600) / 60);
const seconds = Math.floor((train_time%60));
return `${hours} hrs ${minutes} min ${seconds} sec`;
}
Day.js
If you use day.js, try this.
const dayjs = require('dayjs')
const duration = require('dayjs/plugin/duration')
dayjs.extend(duration)
const time = dayjs.duration(100, 'seconds')
time.seconds() // 40
time.minutes() // 1
time.format('mm:ss') // 01:40
I prefer thinking of Millisecond as its own unit, rather than as a subunit of something else. In that sense, it will have values of 0-999, so you're going to want to Pad three instead of two like I have seen with other answers. Here is an implementation:
function format(n) {
let mil_s = String(n % 1000).padStart(3, '0');
n = Math.trunc(n / 1000);
let sec_s = String(n % 60).padStart(2, '0');
n = Math.trunc(n / 60);
return String(n) + ' m ' + sec_s + ' s ' + mil_s + ' ms';
}
console.log(format(241));
https://developer.mozilla.org/Web/JavaScript/Reference/Global_Objects/String/padStart
Here's an ES6 version of the seconds to minutes and seconds conversion, with padding (00:00 format). It only accepts integer values for seconds and ~~(x) is the shorthand floor operation.
const padTime = n => ("" + n).padStart(2, 0);
const secondsToMinSec = time =>
`${padTime(~~(time / 60))}:${padTime(time - ~~(time / 60) * 60)}`
;
for (let i = 0; i < 10; i++) {
const seconds = ~~(Math.random() * 300);
console.log(seconds, secondsToMinSec(seconds));
}
if you need to work with the result easily later this is what I use:
function seconds2hms(seconds, milliseconds) {
if(milliseconds) {
seconds = Math.floor(seconds/1000);
}
return {h:~~(seconds / 3600),m:~~((seconds % 3600) / 60),s:~~seconds % 60}
}
(used Vishal's code)
strftime.js (strftime github) is one of the best time formatting libraries. It's extremely light - 30KB - and effective. Using it you can convert seconds into time easily in one line of code, relying mostly on the native Date class.
When creating a new Date, each optional argument is positional as follows:
new Date(year, month, day, hours, minutes, seconds, milliseconds);
So if you initialize a new Date with all arguments as zero up to the seconds, you'll get:
var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)
You can see that 150 seconds is 2-minutes and 30-seconds, as seen in the date created. Then using an strftime format ("%M:%S" for "MM:SS"), it will output your minutes' string.
var mm_ss_str = strftime("%M:%S", date);
=> "02:30"
In one line, it would look like:
var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"
Plus this would allow you to interchangeable support HH:MM:SS and MM:SS based on the number of seconds. For example:
# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"
# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"
And of course, you can simply pass whatever format you want to strftime if you want the time string to be more or less semantic.
var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"
You've done enough code to track minutes and seconds portions of time.
What you could do is add the hours factor in:
var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);
var mind = hrd % 60;
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
var moreminutes = minutes + hours * 60
I have the duration of a video in seconds 634.567! I have successfully converted this to HH:MM:SS:ms format using this code:
var pad = function(num, size) { return ('000' + num).slice(size * -1); },
time = parseFloat(timeInSeconds).toFixed(3),
hours = Math.floor(time / 60 / 60),
minutes = Math.floor(time / 60) % 60,
seconds = Math.floor(time - minutes * 60),
milliseconds = time.slice(-3);
return pad(hours, 2) + ':' + pad(minutes, 2) + ':' + pad(seconds, 2) + ',' + pad(milliseconds, 3);
This returns "00:10:34,567"
Now, I would like to split this time into intervals of 5 seconds. So, it becomes an JS array that looks like this
00.00.05, 000 | 00.00.10, 000 | 00.00.15, 000 | till the very last line in the array is 00:10:34,567 (so it's all in equal parts).
How do I split the time into smaller times then push it into an array?
For that, it would be probably better to work with the original time duration timeInSeconds, iterate in steps of 5 seconds and convert the corresponding value for each step, e.g.:
var pad = function(num, size) { return ('000' + num).slice(size * -1); };
function conv(t){
var time = parseFloat(t).toFixed(3),
hours = Math.floor(time / 60 / 60),
minutes = Math.floor(time / 60) % 60,
seconds = Math.floor(time - minutes * 60),
milliseconds = time.slice(-3);
return pad(hours, 2) + ':' + pad(minutes, 2) + ':' + pad(seconds, 2) + ',' + pad(milliseconds, 3);
}
var timeInSeconds = 634.567;
//required step
var delta = 5;
/*
the condition (t < timeInSeconds + delta) in combination
with Math.min(t, timeInSeconds) ensures that the for
loop will consider the value timeInSeconds even if it
is not divisible by delta
*/
var arr = [];
for(var t = 0; t < timeInSeconds + delta; t += delta){
arr.push(conv(Math.min(t, timeInSeconds)));
}
console.log(arr);
So for example for timeInSeconds = 11.0, you would get:
[ '00:00:00,000', '00:00:05,000', '00:00:10,000', '00:00:11,000' ]
This is a common problem but I'm not sure how to solve it. The code below works fine.
var mind = time % (60 * 60);
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
However, when I get to 1 hour or 3600 seconds it returns 0 minutes and 0 seconds. How can I avoid this so it returns all the minutes?
To get the number of full minutes, divide the number of total seconds by 60 (60 seconds/minute):
const minutes = Math.floor(time / 60);
And to get the remaining seconds, multiply the full minutes with 60 and subtract from the total seconds:
const seconds = time - minutes * 60;
Now if you also want to get the full hours too, divide the number of total seconds by 3600 (60 minutes/hour · 60 seconds/minute) first, then calculate the remaining seconds:
const hours = Math.floor(time / 3600);
time = time - hours * 3600;
Then you calculate the full minutes and remaining seconds.
Bonus:
Use the following code to pretty-print the time (suggested by Dru):
function str_pad_left(string, pad, length) {
return (new Array(length + 1).join(pad) + string).slice(-length);
}
const finalTime = str_pad_left(minutes, '0', 2) + ':' + str_pad_left(seconds, '0', 2);
Another fancy solution:
function fancyTimeFormat(duration) {
// Hours, minutes and seconds
const hrs = ~~(duration / 3600);
const mins = ~~((duration % 3600) / 60);
const secs = ~~duration % 60;
// Output like "1:01" or "4:03:59" or "123:03:59"
let ret = "";
if (hrs > 0) {
ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
}
ret += "" + mins + ":" + (secs < 10 ? "0" : "");
ret += "" + secs;
return ret;
}
console.log(
fancyTimeFormat(1),
fancyTimeFormat(10),
fancyTimeFormat(100),
fancyTimeFormat(1000),
fancyTimeFormat(10000),
);

// to which we concatenate a String (converts the Number to String)
// who's reference is chosen by the conditional operator:
9 < s // if seconds is larger than 9
? ':' // then we don't need to prepend a zero
: ':0' // else we do need to prepend a zero
) + s ; // and we add Number s to the string (converting it to String as well)
}
Note: Negative range could be added by prepending (0>s?(s=-s,'-'):'')+ to the return expression (actually, (0>s?(s=-s,'-'):0)+ would work as well).
2020 UPDATE
Using basic math and simple javascript this can be done in just a few lines of code.
EXAMPLE - Convert 7735 seconds to HH:MM:SS.
MATH:
Calculations use:
Math.floor() - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor
The Math.floor() function returns the largest integer less than or equal to a given number.
% arithmetic operator (Remainder) - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder
The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend.
Check out code below. Seconds are divided by 3600 to get number of hours and a remainder, which is used to calculate number of minutes and seconds.
HOURS => 7735 / 3600 = 2 remainder 535
MINUTES => 535 / 60 = 8 remainder 55
SECONDS => 55
LEADING ZEROS:
Many answers here use complicated methods to show number of hours, minutes and seconds in a proper way with leading zero - 45, 04 etc. This can be done using padStart(). This works for strings so the number must be converted to string using toString().
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart
The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.
CODE:
function secondsToTime(e){
const h = Math.floor(e / 3600).toString().padStart(2,'0'),
m = Math.floor(e % 3600 / 60).toString().padStart(2,'0'),
s = Math.floor(e % 60).toString().padStart(2,'0');
return h + ':' + m + ':' + s;
//return `${h}:${m}:${s}`;
}
console.log(secondsToTime(7735)); // 02:08:55
/*
secondsToTime(SECONDS) // HH:MM:SS
secondsToTime(8) // 00:00:08
secondsToTime(68) // 00:01:08
secondsToTime(1768) // 00:29:28
secondsToTime(3600) // 01:00:00
secondsToTime(5296) // 01:28:16
secondsToTime(7735) // 02:08:55
secondsToTime(45296) // 12:34:56
secondsToTime(145296) // 40:21:36
secondsToTime(1145296) // 318:08:16
*/
2019 best variant
Format hh:mm:ss
console.log(display(60 * 60 * 2.5 + 25)) // 2.5 hours + 25 seconds
function display (seconds) {
const format = val => `0${Math.floor(val)}`.slice(-2)
const hours = seconds / 3600
const minutes = (seconds % 3600) / 60
return [hours, minutes, seconds % 60].map(format).join(':')
}
You can also use native Date object:
var date = new Date(null);
date.setSeconds(timeInSeconds);
// retrieve time ignoring the browser timezone - returns hh:mm:ss
var utc = date.toUTCString();
// negative start index in substr does not work in IE 8 and earlier
var time = utc.substr(utc.indexOf(':') - 2, 8)
// retrieve each value individually - returns h:m:s
var time = date.getUTCHours() + ':' + date.getUTCMinutes() + ':' + date.getUTCSeconds();
// does not work in IE8 and below - returns hh:mm:ss
var time = date.toISOString().substr(11, 8);
// not recommended - only if seconds number includes timezone difference
var time = date.toTimeString().substr(0, 8);
Of course this solution works only for timeInSeconds less than 24 hours ;)
function secondsToMinutes(time){
return Math.floor(time / 60)+':'+Math.floor(time % 60);
}
To add leading zeros, I would just do:
const secondsToMinSecPadded = time => {
const minutes = "0" + Math.floor(time / 60);
const seconds = "0" + (time - minutes * 60);
return minutes.substr(-2) + ":" + seconds.substr(-2);
};
console.log(secondsToMinSecPadded(241));
Nice and short
Moment.js
If you are using Moment.js then you can use there built in Duration object
const duration = moment.duration(4825, 'seconds');
const h = duration.hours(); // 1
const m = duration.minutes(); // 20
const s = duration.seconds(); // 25
Clean one liner using ES6
const secondsToMinutes = seconds => Math.floor(seconds / 60) + ':' + ('0' + Math.floor(seconds % 60)).slice(-2);
The most concise method I found can be done using in just one line:
let timeString = `${timeInSeconds/60|0}:${timeInSeconds%60}`
Explanation
`${...}`Template literals. Allows for expressions to be converted into a string from within the string itself.Note: Incompatible with IE.
timeInSeconds/60|0Takes the seconds and converts in into minutes (/60). This gives a rational number. From here it is truncated using the bitwise OR (|0)
timeInSeconds%60Remainder (modulo). Gives the remainder of the variable divided by 60.
Hours
This method can be expanded to include hours like this:
let timeString = `${timeInSeconds/60/60|0}:${timeInSeconds/60%60|0}:${timeInSeconds%60}`
Repeating this process, you can even include days.
A one liner (doesnt work with hours):
function sectostr(time) {
return ~~(time / 60) + ":" + (time % 60 < 10 ? "0" : "") + time % 60;
}
Seconds to h:mm:ss
var hours = Math.floor(time / 3600);
time -= hours * 3600;
var minutes = Math.floor(time / 60);
time -= minutes * 60;
var seconds = parseInt(time % 60, 10);
console.log(hours + ':' + (minutes < 10 ? '0' + minutes : minutes) + ':' + (seconds < 10 ? '0' + seconds : seconds));
The Following function will help you to get Days , Hours , Minutes , seconds
toDDHHMMSS(inputSeconds){
const Days = Math.floor( inputSeconds / (60 * 60 * 24) );
const Hour = Math.floor((inputSeconds % (60 * 60 * 24)) / (60 * 60));
const Minutes = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) / 60 );
const Seconds = Math.floor(((inputSeconds % (60 * 60 * 24)) % (60 * 60)) % 60 );
let ddhhmmss = '';
if (Days > 0){
ddhhmmss += Days + ' Day ';
}
if (Hour > 0){
ddhhmmss += Hour + ' Hour ';
}
if (Minutes > 0){
ddhhmmss += Minutes + ' Minutes ';
}
if (Seconds > 0){
ddhhmmss += Seconds + ' Seconds ';
}
return ddhhmmss;
}
alert( toDDHHMMSS(2000));
After all this, yet another simple solution:
const time = new Date(null);
time.setSeconds(7530);
console.log(time.getHours(), time.getMinutes(), time.getSeconds());
Another but much more elegant solution for this is as follows:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* #param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};
function formatSeconds(s: number) {
let minutes = ~~(s / 60);
let seconds = ~~(s % 60);
return minutes + ':' + seconds;
}
For adding zeros I really don't see the need to have a full other function where you can simply use for example
var mins=Math.floor(StrTime/60);
var secs=StrTime-mins * 60;
var hrs=Math.floor(StrTime / 3600);
RoundTime.innerHTML=(hrs>9?hrs:"0"+hrs) + ":" + (mins>9?mins:"0"+mins) + ":" + (secs>9?secs:"0"+secs);
Its why we have conditional statements in the first place.
(condition?if true:if false) so if example seconds is more than 9 than just show seconds else add a string 0 before it.
var seconds = 60;
var measuredTime = new Date(null);
measuredTime.setSeconds(seconds); // specify value of SECONDS
var Time = measuredTime.toISOString().substr(11, 8);
document.getElementById("id1").value = Time;
<div class="form-group">
<label for="course" class="col-md-4">Time</label>
<div class="col-md-8">
<input type="text" class="form-control" id="id1" name="field">Min
</div>
</div>
Try this:
Converting Second to HOURS, MIN and SEC.
function convertTime(sec) {
var hours = Math.floor(sec/3600);
(hours >= 1) ? sec = sec - (hours*3600) : hours = '00';
var min = Math.floor(sec/60);
(min >= 1) ? sec = sec - (min*60) : min = '00';
(sec < 1) ? sec='00' : void 0;
(min.toString().length == 1) ? min = '0'+min : void 0;
(sec.toString().length == 1) ? sec = '0'+sec : void 0;
return hours+':'+min+':'+sec;
}
1 - Get rest of division using %. Now you have the seconds that don't complete a minute
2 - Subtract the seconds obtained in step 1 from the total. Now you have the minutes
For example, let's assume you have 700 seconds:
seconds = 700%60); //40 seconds
minutes = (700 - (700%60))/60; //11
//11:40
I was thinking of a faster way to get this done and this is what i came up with
var sec = parseInt(time);
var min=0;
while(sec>59){ sec-=60; min++;}
If we want to convert "time" to minutes and seconds, for example:
// time = 75,3 sec
var sec = parseInt(time); //sec = 75
var min=0;
while(sec>59){ sec-=60; min++;} //sec = 15; min = 1
Put my two cents in :
function convertSecondsToMinutesAndSeconds(seconds){
var minutes;
var seconds;
minutes = Math.floor(seconds/60);
seconds = seconds%60;
return [minutes, seconds];
}
So this :
var minutesAndSeconds = convertSecondsToMinutesAndSeconds(101);
Will have the following output :
[1,41];
Then you can print it like so :
console.log('TIME : ' + minutesSeconds[0] + ' minutes, ' + minutesSeconds[1] + ' seconds');
//TIME : 1 minutes, 41 seconds
export function TrainingTime(props) {
const {train_time } = props;
const hours = Math.floor(train_time/3600);
const minutes = Math.floor((train_time-hours * 3600) / 60);
const seconds = Math.floor((train_time%60));
return `${hours} hrs ${minutes} min ${seconds} sec`;
}
Day.js
If you use day.js, try this.
const dayjs = require('dayjs')
const duration = require('dayjs/plugin/duration')
dayjs.extend(duration)
const time = dayjs.duration(100, 'seconds')
time.seconds() // 40
time.minutes() // 1
time.format('mm:ss') // 01:40
I prefer thinking of Millisecond as its own unit, rather than as a subunit of something else. In that sense, it will have values of 0-999, so you're going to want to Pad three instead of two like I have seen with other answers. Here is an implementation:
function format(n) {
let mil_s = String(n % 1000).padStart(3, '0');
n = Math.trunc(n / 1000);
let sec_s = String(n % 60).padStart(2, '0');
n = Math.trunc(n / 60);
return String(n) + ' m ' + sec_s + ' s ' + mil_s + ' ms';
}
console.log(format(241));
https://developer.mozilla.org/Web/JavaScript/Reference/Global_Objects/String/padStart
Here's an ES6 version of the seconds to minutes and seconds conversion, with padding (00:00 format). It only accepts integer values for seconds and ~~(x) is the shorthand floor operation.
const padTime = n => ("" + n).padStart(2, 0);
const secondsToMinSec = time =>
`${padTime(~~(time / 60))}:${padTime(time - ~~(time / 60) * 60)}`
;
for (let i = 0; i < 10; i++) {
const seconds = ~~(Math.random() * 300);
console.log(seconds, secondsToMinSec(seconds));
}
if you need to work with the result easily later this is what I use:
function seconds2hms(seconds, milliseconds) {
if(milliseconds) {
seconds = Math.floor(seconds/1000);
}
return {h:~~(seconds / 3600),m:~~((seconds % 3600) / 60),s:~~seconds % 60}
}
(used Vishal's code)
strftime.js (strftime github) is one of the best time formatting libraries. It's extremely light - 30KB - and effective. Using it you can convert seconds into time easily in one line of code, relying mostly on the native Date class.
When creating a new Date, each optional argument is positional as follows:
new Date(year, month, day, hours, minutes, seconds, milliseconds);
So if you initialize a new Date with all arguments as zero up to the seconds, you'll get:
var seconds = 150;
var date = new Date(0,0,0,0,0,seconds);
=> Sun Dec 31 1899 00:02:30 GMT-0500 (EST)
You can see that 150 seconds is 2-minutes and 30-seconds, as seen in the date created. Then using an strftime format ("%M:%S" for "MM:SS"), it will output your minutes' string.
var mm_ss_str = strftime("%M:%S", date);
=> "02:30"
In one line, it would look like:
var mm_ss_str = strftime('%M:%S', new Date(0,0,0,0,0,seconds));
=> "02:30"
Plus this would allow you to interchangeable support HH:MM:SS and MM:SS based on the number of seconds. For example:
# Less than an Hour (seconds < 3600)
var seconds = 2435;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "40:35"
# More than an Hour (seconds >= 3600)
var seconds = 10050;
strftime((seconds >= 3600 ? '%H:%M:%S' : '%M:%S'), new Date(0,0,0,0,0,seconds));
=> "02:47:30"
And of course, you can simply pass whatever format you want to strftime if you want the time string to be more or less semantic.
var format = 'Honey, you said you\'d be read in %S seconds %M minutes ago!';
strftime(format, new Date(0,0,0,0,0,1210));
=> "Honey, you said you'd be read in 10 seconds 20 minutes ago!"
You've done enough code to track minutes and seconds portions of time.
What you could do is add the hours factor in:
var hrd = time % (60 * 60 * 60);
var hours = Math.floor(hrd / 60);
var mind = hrd % 60;
var minutes = Math.floor(mind / 60);
var secd = mind % 60;
var seconds = Math.ceil(secd);
var moreminutes = minutes + hours * 60
The following is a method that converts millisecond to human-readable time. However I got a comment about it that says it might return unexpected result for some radix.
function msToTime(duration, sign) {
var milliseconds = parseInt((duration % 1000) / 100),
seconds = parseInt((duration / 1000) % 60),
minutes = parseInt((duration / (1000 * 60)) % 60),
hours = parseInt((duration / (1000 * 60 * 60)) % 24);
hours = (hours < 10) ? "0" + hours : hours;
minutes = (minutes < 10) ? " " + minutes : minutes;
seconds = (seconds < 10) ? "0" + seconds : seconds;
return minutes + sign + seconds;
}
$("div").text(msToTime(1203400, ":"));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div></div>
This is the comment I have received: "The parseInt() function can return undesired and/or unexpected results if the radix is not supplied.Please make sure a radix is used on all parseInt() instances."
I tried to add day, week, month, year and so on, but I am not sure if that's the right way. Also it is for a duration of music. So there won't be any case for longer than hours I think.
Any idea to make sure the result of the method is always correct?
parseInt() takes a second parameter called radix as its second parameter
An integer between 2 and 36 that represents the radix (the base in
mathematical numeral systems) of the above mentioned string. Specify
10 for the decimal numeral system commonly used by humans. Always
specify this parameter to eliminate reader confusion and to guarantee
predictable behavior. Different implementations produce different
results when a radix is not specified.
Since you are dealing with decimal number system, pass the radix as 10 to solve such a problem
parseInt((duration % 1000) / 100, 10)
Radix is the second parameter parseInt() takes, It's a number (from 2 to 36) that represents the numeral system to be used. You should use 10, as this represents the decimal numeral system.
var milliseconds = (parseInt(duration) % 1000) / 100, 10)
If no radix is passed the following will be used:
If the string begins with "0x", the radix is 16 (hexadecimal).
If the string begins with "0", the radix is 8 (octal). This feature is
deprecated
If the string begins with any other value, the radix is 10
(decimal)
If you don't allways want to specify it, create a function like this:
function parseInt10(val){
return parseInt(val,10);
}
The other answers are offering your some advice about parseInt() which is technically correct, but irrelevant to your actual code because you do not even need to be using parseInt() in your function.
Since it appears you're already passing a number (not a string) into your function, you don't even need ANY parseInt() operations and can simplify it a lot like this:
function msToTime(duration, sign) {
var milliseconds = (duration % 1000) / 100,
seconds = (duration / 1000) % 60,
minutes = (duration / (1000 * 60)) % 60,
hours = (duration / (1000 * 60 * 60)) % 24;
hours = (hours < 10) ? "0" + hours : hours;
minutes = (minutes < 10) ? " " + minutes : minutes;
seconds = (seconds < 10) ? "0" + seconds : seconds;
return minutes + sign + seconds;
}
If you wanted your function to accept either a number or a string passed in for the duration, you could support that like this:
function msToTime(t, sign) {
var duration = +t;
var milliseconds = (duration % 1000) / 100,
seconds = (duration / 1000) % 60,
minutes = (duration / (1000 * 60)) % 60,
hours = (duration / (1000 * 60 * 60)) % 24;
hours = (hours < 10) ? "0" + hours : hours;
minutes = (minutes < 10) ? " " + minutes : minutes;
seconds = (seconds < 10) ? "0" + seconds : seconds;
return minutes + sign + seconds;
}
And, if you did use parseInt(), you would convert duration to a number:
var d = parseInt(duration, 10);
And, then use that value in your calculations. As your code has it now, you are calling parseInt() on the results of a mathematical calculation which means you're calling parseInt on a number which doesn't do anything.
