Are you using Angular 5? Or a previous version? – Management

@shadowlauch Angular 4 – Sakhuja

I'm not exactly sure if this causes the issue and sadly I can't check, because I don't have access to a Mac right now, but Angular 4 uses the intl API and that has caused some issues with Safari. Angular 5 switched away from the intl API for added constiency. – Management

What is the difference? AM and PM? – Remise

@Duannxand it showing Am and it is taking Darwin timezone – Sakhuja

Answer 1

In ios/mac date filter doesn't work, so use moment.js for this.

I have tried lot of stuff but I was able to do best in moment.js

like: I created a pipe

<span>{{ActionDate | dateTimeFormatFilter : "MMM DD, YYYY"}}</span>

@Pipe({name: "dateTimeFormatFilter"})
@Injectable()
export class DateTimeFormatPipe implements PipeTransform {
transform(date: any, format: string): any {
        if (date) {
         return moment(date).format(format);
        }
    }
}

The issue you are facing is caused by the Intlapi because DatePipe for Angular 2 Release is working fine only for FireFox and Chrome with custom format strings. it Doesn't work on Safari due to lack of Intl. so as a temporary work around is to include the Intl polyfill

<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.en"></script>

Solution 2 You can use the moment.js which can format your required date as follows

moment(singleTable[0].FromCurrentDate).format("dd/MM/yyyy,h:mm:ss a")

Update 1

In latest angular they have removed the Intl api , and for this you need to update to the angular 5 , reference

Update 2 Here is a plunker using MomentJs in angular flavor, i added your date format but didn't tested in safari tested in chrome,

Hertzog

if i choose solution2 then on the html side can i use this moment.js – Sakhuja

@Sakhuja yes you can , you can get the tutorials for those implementations also – Hertzog

but how can i give solution2 moment(singleTable[0].FromCurrentDate).format("dd/MM/yyyy,h:mm:ss a") in {{ }} – Sakhuja

@Sakhuja as you are using the angular 2 , better try to use moment which supports modular format , ex : npmjs.com/package/angular2-moment – Hertzog

I ran into the same issue on safari on desktop and safari/chrome on iPhone. It works on safari or mostly all browsers when the date object is used as the value. (DatePipe)

I resolved the same issue by adding a custom pipe to convert the date-time string into date object and then the date pipe works as expected.

Component

someDate1 = "2019-09-01 12:02:14";
someDate2 = "2019-09-01";
someDate3 = "2019-09-01 00:00:00";

Template

{{ someDate1 | toDateObj | date:'MM-dd-yyyy h:mm a' }}

Here is the toDateObj custom pipe I added.

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

@Pipe({
  name: 'toDateObj'
})

export class ToDateObjPipe implements PipeTransform {

    transform(value: any): any {
        if (value) {
            if (value.toString().indexOf(' ') === -1) {
                value = value + ' 00:00:00';
            }
            const temp = value.toString().replace(' ', 'T');
            return new Date(temp);
        } else {
            return null;
        }
    }

}

For me this works on Safari and on Chrome:

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


@Pipe({
  name: 'customDate'
})

export class DatePipe implements PipeTransform {
  transform(value: string): string {

      let dd = value.substr(8, 2);
      let MM = value.substr(5, 2);
      let yyyy = value.substr(0, 4);
      let date = `${dd}.${MM}.${yyyy}`;

      return `${date}`;
  }
}

I had a bug rendering views on Safari when chrome was ok. Later after debugging I found that pipe | date was a problem. So I made custom one. All answers up are great but importing moment library seems like a big file IMHO. Just make this class export, make a module and declare it there(also export it) and use as example: {{_question.created_at | toDateObj: 'dd.MM.yyyy'}}

Hope it helps someone

You need to receive the date with this format "yyyy-MM-ddTHH:mm" ,it will work for all devices and browsers
