Current behavior

import { MomentDateAdapter, MatMomentDateModule } from '@angular/material-moment-adapter'; export const MOMENT_DATE_FORMATS: MatDateFormats = { parse: { dateInput: 'D/MM/YYYY' }, display: { dateInput: 'DD/MM/YYYY', monthYearLabel: 'MMMM Y', dateA11yLabel: 'LL', monthYearA11yLabel: 'MMMM Y' } }; providers: [ {provide: APP_CONFIG, useValue: AppConfig}, { provide: MAT_DATE_LOCALE, useValue: 'fr-FR' }, { provide: MAT_DATE_FORMATS, useValue: MOMENT_DATE_FORMATS}, { provide: DateAdapter, useClass : MomentDateAdapter },
Are set in app.modules.ts.

These providers are not used in the Material Datepicker component of json-schema-form, instead, the default native javascript's Date implementation is used.

Expected behavior

json-schema-form should pass the apps' providers and set the Date implementation accordingly.

IMPORTANT: How can we reproduce your problem?

provide MomentDateAdapter as a DateAdapter, display any form containing a Datepicker : it is still a Date and does not work with the user's locale (no timezone/UTC format, leading to -1 on Dates), as in : Issue
