I have user inputs of meeting_time which is javascript Date (calendar select) and meeting_time string (select dropdown option)
var userTime = meeting_time ? meeting_time.label.split(' -')[0] : null
var userDate = moment(meeting_date).format("YYYY-MM-DD");
How Do I converting those variable to moment.js object with specific timezone
For example,
meeting_date is Thu Jul 12 2018 12:00:00 GMT+0300 (MSK)
meeting_time is 15:00 - 15:30
I want to get moment _d Thu Jul 12 2018 20:00:00 GMT+0800 (UTC +3 to UTC +8)
You can set the hour and minute in the date.
const [hour, minute] = userTime.split(':');
moment(meeting_date).hour(hour).minute(minute).toDate();

Hello i am trying to add time zone offset for start & end date.
In order to get something like this
start date: Mon May 30 2022 05:00:00 GMT+0000 here offset is (00:00 + 5 hours US central time offset)
end time: Wed Jun 01 2022 04:59:00 GMT+0000 (23:59 + 5 hours offset)
But getting for start date Mon May 29 2022 00:00:00 GMT+0000
Here is my code
export function convertIsoToMomentLocal(iso: string | ParsableDate, timezone = 'CST') {
if (iso && timezone) {
const mo = moment.tz(iso, timezone).startOf('day')
const offset = mo.utcOffset()
const epoch = mo.add(offset, 'm').unix()
console.log(epoch, 'test')
return epoch
}
}
So basically i am trying to determine start date and end date first, and only after that add time zone offset.
Any ideas tnx, i have tried everything.
This is how I calculate the duration:
var duration = new Date().getTime() - customerForgotPassword[0].createdTime.getTime();
This is how I compare:
var TEN_MINUTES = 10*60*1000;
if(duration > TEN_MINUTES){
//do smtg
}
new Date().getTime() returns 1528291351108 which is Wed Jun 06 2018 13:22:31 in UTC
customerForgotPassword[0].createdTime returns Wed Jun 06 2018 13:20:04 GMT+0800 (Malay Peninsula Standard Time) in my code.
customerForgotPassword[0].createdTime.getTime() returns 1528262404000 which is Wed Jun 06 2018 05:20:04 in UTC
In database, customerForgotPassword[0].createdTime is in UTC format but when I retrieve it, it shows the local timezone. How can I set this to UTC format too when I retrieve it in node.js using Sequelize ?
I had to add 8 hours to get time in UTC
var timeInUTC = customerForgotPassword[0].createdTime.getTime() - (customerForgotPassword[0].createdTime.getTimezoneOffset() * 60 * 1000)
I need to store an unix value from a Time input.
The problem is that :
// I create a Moment Date from my input :
var date = moment({hour: 10, minute: 00)
// gives this _d : Mon May 04 2015 10:00:00 GMT+0200 (CEST)
// I convert it to unix value
date = date.unix()
// -> 1430726400
moment( date ).format('HH:mm')
// -> "14:25" // Should give me 10:00
// Online conversion unix time gives me : Mon, 04 May 2015 08:00:00 GMT
So how can I keep my 10:00 in memory as unix value using those transformations ?
Per documentation:
moment.unix( date ).format('HH:mm')
I kind of sorted it this way :
// I create a Moment Date from my input :
var date = moment({hour: 10, minute: 00)
// gives this _d : Mon May 04 2015 10:00:00 GMT+0200 (CEST)
// Convert to unix
date = date.toDate();
date = date.getTime();
console.log(moment( date ).format('HH:mm')); // Gives me 10:00
I hope it will keep the good time ? In France the time changes twice a year ( go forward 1 hour, go backwards 1 hour)
I have this string "Mon Oct 21 2013 21:00:00 GMT-0300 (ART)" and I need to convert it to the timezone (GMT-0300) using just moment.js (not moment-timezone.js)
I'm doing this but it's returning the same hour.
var startDateTime = moment(date).format('YYYY-MM-DD HH:mm Z'),
startMoment = moment.parseZone(startDateTime).zone();
console.log(moment(startDateTime).zone(startMoment).format("YYYY-MM-DD HH:mm"));
Any help ?
To convert a moment object with timezone A to timezone B, you can do the following:
var startDateTime = "Mon Oct 21 2013 21:00:00 GMT-0300 (ART)";
var newDateTime = moment(startDateTime).zone('-0400').format('YYYY-MM-DD HH:mm')
Also note that in your example, the initial time "Mon Oct 21 2013 21:00:00 GMT-0300 (ART)" is already GMT-0300.
I get time in milliseconds from the server. I convert it to Date and get -
Mon Jul 22 2013 11:16:01 GMT+0200 (W. Europe Daylight Time) as the date in the record.
I want to separate out data of Monday, Tuesday etc into arrays. I am thinking of converting this date to Mon Jul 22 2013 23:59:59 GMT+0200 (W. Europe Daylight Time) and then filter out the records.
How can i change the date to the required end of the day time? or is there an easier way to do this ?
You could always construct a new DateTime object just using the year, month and day properties from the existing date, like so:
var actualDate = new Date(); // 2013-07-30 17:11:00
var endOfDayDate = new Date(actualDate.getFullYear()
,actualDate.getMonth()
,actualDate.getDate()
,23,59,59); // 2013-07-30 23:59:59
For future visitors, just use
var start = new Date();
var end = new Date();
start.setHours(0,0,0,0);
end.setHours(23,59,59,999);
Using http://momentjs.com:
var now = new Date().getTime();
var endOfDay = moment(now).endOf("day").toDate(); // Wed Jan 20 2016 23:59:59 GMT-0800 (PST)
var actualDate = new Date()
var eodDate = new Date(Math.floor(actualDate.getTime()/86400000+1)*86400000 + actualDate .getTimezoneOffset()*60000 - 1000)
where 86400000 are total milliseconds in a day
If two Date Objects are on the same day then they have the same Date String:
new Date('1374488161000').toDateString()
=> "Tue Jul 30 2013"
new Date('13744917610403').toDateString()
=> "Tue Jul 30 2013"
Although a rather naive method of comparing days, it's probably the simplest comparison.
