MomentJS/Date object UTC by default

Question

I am using MomentJS in my angular project and i\'m having a lot of issues with different date timezones.

My app should not take into consideration any timezones, how

Answer 1

You can use moment-timezone with moment.

And then set default UTC timezone with code below:

import * as moment from 'moment-timezone';
...
moment.tz.setDefault('Etc/UTC');

A possible option in Angular could be to create a singleton instance LocaleService to manage localization related parameters.

import { Injectable } from '@angular/core';
import * as moment from 'moment-timezone';

@Injectable({
  providedIn: 'root'
})
export class LocaleService {

  constructor() {
    this.setDefaultTimezone();
  }

  setDefaultTimezone() {
    moment.tz.setDefault('Etc/UTC');
  }

  // other stuff related to localization
  ...setCurrentTimezone()
  ...setLocale()
}

And then, we need to provide this service via AppModule, and also don't forget to inject it in a global component, for instance AppComponent, in order to be instantiated.
