How can I customize date and time format in ngx-mat-datetime-picker?

Question

I am working on Angular7 and its compatible ngx-mat-datetime-picker. It works as expected.

Want to customize the format:

Actual: mm/dd/yyyy, hh:mm:ss Expected: yyyy-mm-dd hh:mm:ss

Currently I don't find any option for formatting.

I tried something like this in template value="{{ mydate | date: 'yyyy-mm-dd hh:mm:ss' }}

But not working.

You need to create a custom adapter and specify the custom formats

const CUSTOM_DATE_FORMATS: NgxMatDateFormats = {
  parse: {
    dateInput: 'l, LTS'
  },
  display: {
    dateInput: 'YYYY-MM-DD HH:mm:ss',
    monthYearLabel: 'MMM YYYY',
    dateA11yLabel: 'LL',
    monthYearA11yLabel: 'MMMM YYYY',
  }
};

@NgModule({
  providers: [
    {
      provide: NgxMatDateAdapter,
      useClass: CustomNgxDatetimeAdapter,
      deps: [MAT_DATE_LOCALE, NGX_MAT_MOMENT_DATE_ADAPTER_OPTIONS]
    },
    { provide: NGX_MAT_DATE_FORMATS, useValue: CUSTOM_DATE_FORMATS }
  ],
})
export class CustomNgxDateTimeModule { }

Please find the CustomNgxDatetimeAdapter.ts from the below gist
