Setting default time zone is ignored by moment

[ramik91]

I upgraded moment-timezone to 0.5.31 and moment to 2.27.0 in our React project. Tests started to fail due to issue described below. Is it now necessary to use moment-timezone imports only in order to get timezone aware date object?

Repro steps:

import momentTimezone from 'moment-timezone';
import moment from 'moment';

momentTimezone.tz.setDefault('America/Chicago');

const tzDate = momentTimezone('2019-06-25T12:30:00+00:00');
const date = moment('2019-06-25T12:30:00+00:00');


console.log('tzDate:,' tzDate.format('M/D/YYYY h:mm A'));
console.log('date:', date.format('M/D/YYYY h:mm A'));

Result:

tzDate: 6/25/2019 7:30 AM
date: 6/25/2019 12:30 AM

Expected:

tzDate: 6/25/2019 7:30 AM
date: 6/25/2019 7:30 AM

I am also getting my local system timezone after setting another default timezone.

Me too. I have traced the error to the [email protected] version. [email protected] works just fine.

I'm pretty sure this is the same as #892

Closing this in favor of the other one, please check with latest moment/moment-timezone, also I see you're using new js module system (which means there is some compat layer). Try with regular require in a new project (with no other dependencies), if the problem is gone it's likely due to multiple moment versions.
