谢谢你的回答我注意到我的nestjs服务在本地时区存储我的数据，当我检索它时，我的服务将其发送到UTC我用

autoLoadEntities: true,
entities: [],
synchronize: true,
timezone: 'UTC',

现在，当我更改日期时，我将其设置为UTC

this.userTimeZone = Intl.DateTimeFormat().resolvedOptions().timeZone;    
if (parameterToUpdate.callDate != null) {
       const utcCallDate = zonedTimeToUtc(new Date(this.formEdit.value.callDate), this.userTimeZone);
              parameterToUpdate.callDate = (new Date(utcCallDate)).toISOString();
            }

但问题仍然存在，当我检索我的值时。输入正确，但我的日期选择器小时不正确

let zonedDate = utcToZonedTime(data.callDate, this.userTimeZone);
if (data.callDate == null) { this.formEdit.controls.callDate.setValue(null); }
          else {
            this.formEdit.controls.callDate.setValue(zonedDate.toISOString());    
          }

我已使用解决问题

import { formatISO, parseISO } from 'date-fns';

我已经从后端删除了时区

synchronize: true,
//timezone: 'utc'

在我的前端，当我从数据库中检索值时

if (data.checkInStartDate == null) { this.formEdit.controls.checkInStartDate.setValue(null); }
 else { this.formEdit.controls.checkInStartDate.setValue(formatISO(new Date(data.checkInStartDate))); }

更新前端值时

setNow() {
    this.today = formatISO(new Date());
    this.formEdit.controls.checkInStartDate.setValue(this.today);
}

当我将值发送到后端服务时：

if (parameterToUpdate.checkInStartDate != null) {
          parameterToUpdate.checkInStartDate = formatISO(new Date(this.formEdit.value.checkInStartDate));
        }
