Is it possible that in different Android devices time was measured differently?
In the database I save time in UTC
in the reactive native application, I save the time as new Date()
I COUNT THE DIFFERENCE OF TIME FOR TIMES IN THE SAME MOMENT
RESULTS:
the emulator is 0 days and 0 hours (OK)
the smartphone is -1 days and 23 hours (??)
let date = new Date(dateTimeDone);
var today = new Date();
today.setHours(today.getHours());
seconds = Math.floor((today - (date)) / 1000);
minutes = Math.floor(seconds / 60);
hours = Math.floor(minutes / 60);
days = Math.floor(hours / 24);
hours = hours - (days * 24);

I am getting the elapsed time in minutes, hours and days, between two dates, a past date and the current one, I already get this data, but I want this data to change as the minutes, days and hours increase. For example, when I get to 60 minutes, the time changes to 1 hour and the minutes go to 0, when 24 hours go by, these hours change to a day and the hours go back to 0, and so on, the data I get keeps increasing , how can I do this?
const calculateDate = () => {
const date = new Date('Sun Sep 01 2022 01:32:06 GMT-0500');
const currentDate = new Date();
const minutes= Math.floor((currentDate.getTime() - date.getTime()) / 1000 / 60);
const hours= Math.floor((currentDate.getTime() - date.getTime()) / 1000 / (3600));
const days= Math.floor((currentDate.getTime() - date.getTime()) / (1000*60*60*24));
}
With this, get the minutes, hours and days, but how would you update so that when you reach 60 minutes it goes to one hour and 24 hours to one day?
The JavaScript Date object has built in functions for what you want to do.
var now = new Date()
var h = now.getHours()
var m = now.getMinutes()
var s = now.getSeconds()
The new Date created in above example is set to the time it was created.
You can get the current time using the Date object itself:
var current = Date()
With your method you always see the full duration just in a different unit.
You have to use the modulo operator to get only the "missing part" (the remainder of the division) to the next unit:
const date = new Date('Sun Sep 01 2022 01:32:06 GMT-0500');
const currentDate = new Date();
const dateDiff = (currentDate.getTime() - date.getTime()) / 1000;
const seconds = Math.floor(dateDiff) % 60;
const minutes = Math.floor(dateDiff / 60) % 60;
const hours = Math.floor(dateDiff / (60 * 60)) % 24;
const days = Math.floor(dateDiff / (60 * 60 * 24));
I'm using date-fns. I need to create a countdown to the next 10th of the month.
For example, if today is 5th Feb, then the countdown should be to 10th Feb. If today is say 15th Feb, then it should count to 10th March, and so on.
How can I do this with date-fns or even with plain javascript?
You must first find the target date, like this one:
const today = startOfToday();
let target = setDate(today, 10);
if (isBefore(target, today)) {
target = addMonths(target, 1);
}
Then calculate time remaining until the target:
const diff = differenceInSeconds(target, new Date());
const days = Math.floor(diff / 86400);
const hours = Math.floor((diff - days * 86400) / 3600);
const minutes = Math.floor((diff - days * 86400 - hours * 3600) / 60);
const seconds = diff - days * 86400 - hours * 3600 - minutes * 60;
Use days, hours, minutes, seconds for create a countdown. Don't forget to import required functions from date-fns.
I need to change my return time settings from hours to days.
I've tried to expand the hours but I keep getting errors.
let totalSeconds = (client.uptime / 1000);
let hours = Math.floor(totalSeconds / 3600);
totalSeconds %= 3600;
let minutes = Math.floor(totalSeconds / 60);
let seconds = totalSeconds % 60;
// Then you'll have hours, minutes and seconds ready to use.
let uptime = `${hours} hours, ${minutes} minutes and ${seconds} seconds`;
I just keep getting errors.
Converting hours to days would be extremely simple - you just divide by 24 and floor it:
var days = Math.floor(hours / 24);
Hopefully this helps!

I have two dates as like one is 2016-02-23 15:12:12 and another one is 2016-02-29 18:16:42 then how to display hh:mm:ss countdown to subtract this two dates using jquery
Please help Thanks in advance
You try like this
var timer;
var compareDate = new Date();
compareDate.setDate(compareDate.getDate() + 7); //just for this demo today + 7 days
timer = setInterval(function() {
timeBetweenDates(compareDate);
}, 1000);
function timeBetweenDates(toDate) {
var dateEntered = toDate;
var now = new Date();
var difference = dateEntered.getTime() - now.getTime();
if (difference <= 0) {
// Timer done
clearInterval(timer);
} else {
var seconds = Math.floor(difference / 1000);
var minutes = Math.floor(seconds / 60);
var hours = Math.floor(minutes / 60);
var days = Math.floor(hours / 24);
hours %= 24;
minutes %= 60;
seconds %= 60;
$("#days").text(days);
$("#hours").text(hours);
$("#minutes").text(minutes);
$("#seconds").text(seconds);
}
}
or
you can use countDownjs
http://countdownjs.org/demo.html
Note : better to use 3rd party library because someone wrote code for this you better plug it and start using do not waste time when you have some resource for that.
There are two problems you're looking to solve here.
How do you get the difference between two Date objects in javascript
How do you display that difference in hours, minutes, seconds
Get difference between two Date objects in javascript
First, you need to get the Unix timestamp of each Date object, which is the total number of elapsed seconds from the epoch. Then you can subtract these two values to get the total difference in seconds. To do this we rely on Date's getTime() method, which in javascript returns the number of milliseconds since the epoch.
var start = new Date('2016-02-12 15:12:12');
var end = new Date('2016-02-22 18:16:42');
/* This gives us an integer value of the difference in seconds */
var diff = Math.round((end.getTime() - start.getTime()) / 1000);
Display the difference in hours, minutes, and seconds
The second part requires doing some basic clock arithmetic to get the number of hours, minutes, and seconds from the diff value.
Since there are 3600 seconds in an hour, the total number of hours in this value are Math.floor(diff / 3600). Since there are 60 seconds in every minute, the total number of minutes in this value are Math.floor((diff - (hours * 3600)) / 60), where diff is less the number of hours multiplied by 3600. Subsequently the total number of seconds in this value are just the remainder of the diff, less hours and minutes, from the quotient 60 ((diff - hours * 3600) - (minutes * 60) % 60), which we get from the modulus operator.
function getClock(seconds) {
var hours = Math.floor(diff / 3600);
diff -= hours * 3600
var minutes = Math.floor(diff / 60);
diff -= minutes * 60;
var seconds = diff % 60;
return hours + ":" + minutes + ":" + seconds;
}
Putting it all together
If you want to display countdown clocks like this there are some nifty jquery plugins jQuery Countdown which make this process a lot easier. But I felt it important to explain the details behind the programming, none-the-less.
var date1="2016-02-12 15:12:12";
var date2="2016-02-22 18:16:42";
var d1= date1.split(" ");
d1=d1[1];
var d2= date2.split(" ");
d2=d2[1];
d1=d1.split(":");
d2=d2.split(":");
var hours=d2[0]-d1[0];
var mins=d2[1]-d1[1];
var sec=d2[2]-d1[2];
var countdown=hours+":"+mins+":"+sec;
console.log(countdown);
this will give you time remaining.there are some libs for time countdown.you can use use them
Currently I am working on JavaScript, jQuery, HTML5 to improve myself. I have a opensourcely coded clock, which I have converted it into a counter (reverse counter).
Problem I am having is, in my setInterval(){...} I have four variables -> second,min,hour, and day. The problem is, when I get the seconds, I get something like 1.155, 2.312, 3.412 (seconds).
My setInterval function is below
setInterval(function(){
//var duration = parseInt(Date.now() /1000 ) - 1365470000;
var futureTime = Date.parse('April 10, 2013 22:00:00');
var duration = (( parseInt(Date.now() - futureTime ) / 1000));
var seconds = duration % 60;
duration = parseInt(duration / 60);
var minutes = duration % 60;
duration = parseInt(duration / 60);
var hours = (duration)%24;
duration = parseInt(duration / 24);
var days = duration % 365;
animation(gVars.green, seconds, 60);
animation(gVars.blue, minutes, 60);
animation(gVars.orange, hours, 24);
animation(gVars.red, days, 365);
},1000);
}
And my output is below for some random time since i use parseInt(Date.now()).
I have to give the link since I don't have enough rep.

How can I get rid of the decimal point in setInterval(){} functions?
Thanks in advance.
JavaScript offers more convinient API to work with date and time in order to fetch seconds, minutes, hours and days. Try this code:
var duration,
seconds,
minutes,
hours;
duration = new Date((new Date('April 11, 2013 23:00:00')) - (new Date()));
seconds = duration.getSeconds();
minutes = duration.getMinutes();
hours = duration.getHours();
Now you will have integer values in all 4 variables above, without any decimal point.
var seconds = 1234.13;
var seconds = seconds + '';
seconds = seconds.split('.')[0];
console.log(seconds);
