Angular Material использует moment.js для настройки формата даты, как это объяснено здесь
Чтобы заставить его работать, попробуйте следующее:
...
import {MAT_MOMENT_DATE_FORMATS, MomentDateAdapter} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';
// Depending on whether rollup is used, moment needs to be imported differently.
// Since Moment.js doesn't have a default export, we normally need to import using the `* as`
// syntax. However, rollup creates a synthetic default module and we thus need to import it using
// the `default as` syntax.
import * as _moment from 'moment';
// tslint:disable-next-line:no-duplicate-imports
import {default as _rollupMoment} from 'moment';
const moment = _rollupMoment || _moment;
/** @title Datepicker that uses Moment.js dates */
@Component({
...
providers: [
// `MomentDateAdapter` and `MAT_MOMENT_DATE_FORMATS` can be automatically provided by importing
// `MatMomentDateModule` in your applications root module. We provide it at the component level
// here, due to limitations of our example generation script.
{provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},
{provide: MAT_DATE_FORMATS, useValue: MAT_MOMENT_DATE_FORMATS},
],
})
export class DatepickerMomentExample {
// Datepicker takes `Moment` objects instead of `Date` objects.
date = new FormControl(moment([2017, 0, 1]));
}
