Moment.js doesn't show correct time - momentjs

Question

When running my node.js project locally on my computer, moment.js is showing correct time (2019-10-28T07:00:00.000Z because moment have adjusted for DST +02:00 in april and +01:00 in october)):

_z: null }
But on my server, I get this:
Moment {
_isAMomentObject: true,
_i: '2019-04-15T06:00:00.000Z',
_f: 'YYYY-MM-DDTHH:mm:ss.SSSSZ',

_dayOfMonthOrdinalParseLenient: /\d{1,2}(th|st|nd|rd)|\d{1,2}/ },
_a: [ 2019, 3, 15, 6, 0, 0, 0 ],
_d: 2019-10-28T06:00:00.000Z,
_isValid: true,
_z: null }
The date is incorrectly set to 2019-10-28T06:00:00:000Z.
I have set the timezone on the server with sudo timedatectl set-timezone Europe/Oslo
If I am using moment.isDST() for dates on the server, it correctly gives my true in April and false in October.
I am unsure how to solve this, on the server or in my code?

Answer 1

I think I solved it. By answering the from Styx questions, I finally realized that the server app running in a docker container didn't have the correct timezone. By setting environment: TZ: "Europe/Oslo" in the docker-compose.yml file this fixed the problem, and I am getting correct time now.
