Moment Fromnow Returns In 5 Hours When Parsing Utc

trying to format utc time from server in time ago using moment.js fromNow but in some occasions I get 'in 5 hours' instead. timestamp from a server - 2017-11-29T15:03:21 var utcTim

Solution 1:

If you want "2017-11-29T15:03:21" treated as UTC, you can either use moment's utc method or just append a "Z" to the string. Since you're already using moment.js, it's more reliable to parse it with moment.js than the built-in parser:

var timestamp = "2017-11-30T00:20:48";

// Append Zconsole.log(moment(timestamp + 'Z').fromNow());

// Use .utcconsole.log(moment.utc(timestamp).fromNow());

Solution 2:

You need to tell moment that this date is in UTC using moment.utc

var utcTime = newDate(timestamp);
var timeAgo = moment.utc(utcTime).fromNow();

If you don't, moment assumes this date is in your local timezone (which I can tell is Eastern Standard Time by the offset).

In your local timezone, this date is actually 5 hours in the future. Only in UTC is it a few seconds ago, because your local timezone is 5 hours behind UTC.

Solution 3:

As per documents https://momentjs.com/docs/#/displaying/fromnow/

you can customize the locale https://momentjs.com/docs/#/customization/relative-time/

As default locale future time will be future: "in %s", having in which is as per documents. if you want to change it then update the locale and use as you want.

Hope this helps
