Moment.Js: Offsetting dates using UTC and Timezone offset

rated 0 times [ 51] [ 7] / answers: 1 / hits: 43974 / 11 Years ago, wed, january 15, 2014, 12:00:00

I am trying to adjust a time using a timezone offset and a UTC timestamp.

I am running the following code:

var date = {

    utc: '2013-10-16T21:31:51',

    offset: -480

}



var returnDate = moment(date.utc).utc().zone(date.offset).format('MM/DD/YYYY h:mm A');

What I am expecting is: 10/16/2013 1:31 PM but I am ending up with 10/17/2013 9:31 AM

Here is what worked for me:

var date = {

  utc: '2013-10-16T21:31:51',

  offset: 480

}



var returnDate = moment.utc(date.utc).zone(date.offset).format('MM/DD/YYYY h:mm A');

If you noticed, I changed the offset to a positive number. This gave the desired result. If the offset was left at -480 the output was 10/17/2013 5:31 AM.

There is a moment#UTC method that initializes the date as UTC vs. local time.
