Error: Conversion of "2018-01-01-12:12:12:123456" to a date is not possible for the 'DatePipe' filter

 <td>{{suite.testSuiteAttributes && 
       suite.testSuiteAttributes.modifiedTimestamp | date: 'yyyy-MM-dd'
     }}
</td>

I am trying to display the date in the "05-Feb-2018 11:00:00 PM CST" CST format, but I keep getting an error:

Unable to convert "2018-01-01-12:12:12:123456" into a date for the Pipe 'DatePipe'

I believe the issue stems from the fact that the timeStamp is not in the correct date format. The backend is only providing this specific date. Any suggestions on how to handle this?

Answer №1

It appears that the date format you are receiving from the server is incorrect. In order to convert it, you will need a valid date format.

To address this issue, I have created a workaround solution by implementing a myDateParser() method. This method can convert your invalid date into a valid one.

your.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';
  modifiedTimestamp;

 constructor(){

   // Passing unformatted date
   this.modifiedTimestamp = this.myDateParser('2018-01-01-12:12:12:123456');
 }

 /**
  * Custom Date parser

  */
  myDateParser(dateStr : string) : string {
    // Converting to a valid date format - e.g., 2018-01-01T12:12:12.123456;

    let date = dateStr.substring(0, 10);
    let time = dateStr.substring(11, 19);
    let millisecond = dateStr.substring(20)

    let validDate = date + 'T' + time + '.' + millisecond;
    console.log(validDate)
    return validDate
  }
}

your.component.html

  <table>
    <tr>
     <td>{{modifiedTimestamp |  date: 'yyyy-MM-dd'}}</td>
    </tr>
   </table>

I hope this solution proves useful for you!

Answer №2

It appears that the date "2018-01-01-12:12:12:123456" you provided is not in the correct format according to ISO 8601 standards, therefore it cannot be processed by the default parser. You will need to either input a valid date format or create a custom parser.

You have the option of using regex or utilizing string manipulation functions such as substring, as shown in another answer.

In Javascript, dates are displayed in the local time zone of the user's browser, which corresponds to the system time of the user. There isn't a built-in method to create a date in a different timezone. To work with UTC and convert it to a specific timezone, you can utilize the toLocaleString() method. This process will only be accurate if the date received from the backend is in CT (Central Time) timezone.

let result = "2018-01-01-12:12:12:123456".match(/(\d{4})-(\d{2})-(\d{2})-(\d{2}):(\d{2}):(\d{2}):(\d{3})/).map(x => parseInt(x, 10));

result.shift();

console.log(new Date(...result).toLocaleString())
