Angular 4 Date Pipe converting wrongly

Question

I have rest service which returns a collection of objects and one of the field of the item is a date string (ISO-8601 format ) and the date value as follows

Answer 1

You may need to create a UTC date from your date with timezone... I assume you are in the pacific timezone as the time is 7 hours from UTC...

Try this code to get a new date object without Timezone (assuming your variable is named "date"):

var datewithouttimezone = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());

Answer 2

I used moment.js in this scenario. it worked for me. The angular version is 8

import { Pipe, PipeTransform } from '@angular/core';
import * as moment from 'moment';

@Pipe({
  name: 'utcDate'
})
export class UtcDatePipe implements PipeTransform {

  transform(value: string): any {

    if (!value) {
      return '';
    }

    const dateWithNoTimezone = new Date(moment.utc(value).format());

    return dateWithNoTimezone;
  }
}

HTML:

<small class="text-muted ml-auto">{{n.createdAt | utcDate | date :'dd/MM/yyyy h:mm a '}}</small>

Answer 3

You can pass another param to date pipe as follows:

{{resultItem.createdDate | date : 'short' : 'UTC'}}

This param can be a timezone like '-0430' or just 'GMT'

See documentation: https://docs.angularjs.org/api/ng/filter/date

Answer 4

I resolved the issue by adding a custom pipe.

My custom pipe is based on the solution provided by Birwin. Thanks Birwin.

Here is my custom pipe named UtcDate

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'utcDate'
})
export class UtcDatePipe implements PipeTransform {

  transform(value: string): any {

    if (!value) {
      return '';
    }

    const dateValue = new Date(value);

    const dateWithNoTimezone = new Date(
      dateValue.getUTCFullYear(),
      dateValue.getUTCMonth(),
      dateValue.getUTCDate(),
      dateValue.getUTCHours(),
      dateValue.getUTCMinutes(),
      dateValue.getUTCSeconds()
    );

    return dateWithNoTimezone;
  }
}

And I also used default date pipe to format

{{createdDate | utcDate | date:'short'}}
