角度材料datepicker中的日期不正确

当我选择一个日期时,我在字段中看到了正确的日期,但是,当我保存时,日期选择器发送我选择的日期前一天(3小时偏移)
我使用角度反应形式和MatMomentDateModule作为日期选择器.

问题与时区有关,但我只想保存用户输入数据库的相同日期.

代码在这里重新编写：https://stackblitz.com/edit/angular-material-moment-adapter-example-kdk9nk?file=app%2Fapp.module.ts

与githup相关的问题：

任何帮助表示赞赏,我认为很多开发人员需要一个解决方案.

两天前,在 https://github.com/angular/material2/issues/7167,Silthus发布了他的解决方法,覆盖了MomentJsD​​ataAdapter.我尝试过它,它可以作为全球任何地方的魅力.

首先,他添加了MomentUtcDateAdapter,扩展了MomentDateAdapter

import { Inject,Injectable,Optional } from '@angular/core';
import { MAT_DATE_LOCALE } from '@angular/material';   
import { MomentDateAdapter } from '@angular/material-moment-adapter';
import { Moment } from 'moment';
import * as moment from 'moment';

@Injectable()
export class MomentUtcDateAdapter extends MomentDateAdapter {

  constructor(@Optional() @Inject(MAT_DATE_LOCALE) dateLocale: string) {
    super(dateLocale);
  }

  createDate(year: number,month: number,date: number): Moment {
    // Moment.js will create an invalid date if any of the components are out of bounds,but we
    // explicitly check each case so we can throw more descriptive errors.
    if (month < 0 || month > 11) {
      throw Error(`Invalid month index "${month}". Month index has to be between 0 and 11.`);
    }

    if (date < 1) {
      throw Error(`Invalid date "${date}". Date has to be greater than 0.`);
    }

    let result = moment.utc({ year,month,date }).locale(this.locale);

    // If the result isn't valid,the date must have been out of bounds for this month.
    if (!result.isValid()) {
      throw Error(`Invalid date "${date}" for month with index "${month}".`);
    }

    return result;
  }
}

然后在AppModule组件中,您必须这样做：

providers: [
    ...
    { provide: MAT_DATE_LOCALE,useValue: 'en-GB' },{ provide: MAT_DATE_FORMATS,useValue: MAT_MOMENT_DATE_FORMATS },{ provide: DateAdapter,useClass: MomentUtcDateAdapter },...
],
