angular - Tempus Dominus Bootstrap 4 言語/ロケールを変更する

Question

TempusDominusBootstrap 4のオプションで、locale: moment.locale ('ru')最初に次の依存関係を接続して ( ) でロケールを設定しました( import * asmoment from 'moment'; import 'moment / locale / en'; import 'moment-timezone';) 期待した結果が得られません - インターフェイス言語は英語で、GMT ( Thursday, July 19, 2018, 19:13:57) の形式で時刻を取得しますが、タイムゾーンを考慮する必要があります ( четверг, 19 июля 2018 г., 22:13:57 GMT+03:00 DST)。これはどのように修正できますか？

import {Component, OnInit} from '@angular/core';
import * as moment from 'moment';
import 'moment/locale/ru';
import 'moment-timezone';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {

  options = {
    locale: moment.locale('ru'),
    format: 'YYYY/MM/DD HH:mm:ss',
    buttons: {showClear: true},
    icons: {clear: 'fa fa-trash'}
  };
  date = null;

  constructor() {
  }

  ngOnInit() {
    this.date = moment().format('LTS');
  }

  addTime(val, selector) {
    this.date = moment(this.date.add(val, selector));
  }

  clearTime() {
    this.date = null;
  }

  getTime() {
    window.alert('Selected time is:' + this.date.format('YYYY/MM/DD HH:mm'));
  }
