Angular 8 - Datepicker and timepicker

I have been looking at the ngx-bootstrap components for Angular lately. These components are very nice and similar to the components that Bootstrap provides, for Angular. I have tested it out with Angular 8. First off, we import the datepicker and time picker of this library like this: ng add ngx-bootstrap --components datepicker ng add ngx-bootstrap --components timepicker Inside your app.module.ts, you should see the two components imported:
import { BsDatepickerModule } from "ngx-bootstrap/datepicker";
import { TimepickerModule } from 'ngx-bootstrap/timepicker';

It is also included to the imports. My sample projects app.module.ts looks like this:
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { NgModule } from "@angular/core";
import { HttpClientModule } from "@angular/common/http";
import { AppComponent } from "./app.component";
import { UserSettingsFormComponent } from "./user-settings-form/user-settings-form.component";
import { AppFocusDirective } from "./data/app-focus.directive";
import { ButtonsModule } from "ngx-bootstrap/buttons";
import { BsDatepickerModule } from "ngx-bootstrap/datepicker";
import { BsLocaleService } from 'ngx-bootstrap/datepicker';
import { BrowserAnimationsModule } from "@angular/platform-browser/animations";
import { defineLocale } from "ngx-bootstrap/chronos";
import { nbLocale } from "ngx-bootstrap/locale";
import { TimepickerModule, TimepickerConfig } from 'ngx-bootstrap/timepicker';
import { getTimepickerConfig  } from './TimepickerConfig';

defineLocale("nb", nbLocale);

@NgModule({
  declarations: [AppComponent, UserSettingsFormComponent, AppFocusDirective],
  imports: [
    BrowserModule,
    FormsModule,
    HttpClientModule,
    ButtonsModule.forRoot(),
    BsDatepickerModule.forRoot(),
    BrowserAnimationsModule,
    TimepickerModule.forRoot()
  ],
  providers: [ BsLocaleService,
   { provide: TimepickerConfig, useFactory: getTimepickerConfig }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {

  constructor(private bsLocaleService: BsLocaleService) {
    this.bsLocaleService.use('nb');
  }
}

Observe the localization adjustments I have included here, for Norwegian localization of the date picker. I also include a custom factory function for setting up the time picker to not show the meridian button, i.e. show a 24 hours format of the time.
import { TimepickerConfig } from "ngx-bootstrap/timepicker";

// such override allows to keep some initial values

export function getTimepickerConfig(): TimepickerConfig {
  return Object.assign(new TimepickerConfig(), {
    hourStep: 2,
    minuteStep: 5,
    showMeridian: false,
    readonlyInput: false,
    mousewheel: true,
    showMinutes: true,
    showSeconds: false
  });
}


If you want to test out the adjustments I made, the Github repo is available here: https://github.com/toreaurstadboss/Angular8FormsNgxBootstrapTesting
