Moment Locale Not Set Correctly

We're trying to find a problem with tests that use moment.js and fail when run on a server in Arizona but succeed when run locally here in the UK. We manually set the locale before

Solution 1:

Locale and timezone are orthogonal things. A locale does not specify a timezone unambigously. You need to set your timezone separately. You can use Momemt Timezone, and then you can use e.g.

.tz('Europe/London')

Solution 2:

By setting moment.locale('en-gb') you have specified a locale/language (brittish-english), not a timezone.

To specify a timezone you need to include the Moment.js Timezone library in your project, and then do something like:

console.log(moment('2016-05-01T00:00:00+00:00').tz('America/Phoenix').format());

The above will give you the timezone for Arizona.

Solution 3:

After reading more I believe parseZone is the correct solution, given that I am already including Time Zone information in the date string.

console.log(moment.parseZone('2016-05-01T00:00:00+00:00').format());
