java.time.format.DateTimeParseException: Text could not be parsed at index 21

Question

I get the datetime value as

created_at  '2012-02-22T02:06:58.147Z'
Read-only. The time at which this task was created.

Which is given by Asana API

I am using Java 8 to parse the date time as following

import java.time.*;
import java.time.format.*;

public class Times {

  public static void main(String[] args) {
    final String dateTime = "2012-02-22T02:06:58.147Z";
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'hh:mm:ss.SX");


    final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);
    System.out.println(parsed);
  }
}

When I run this, I get the following error

Exception in thread "main" java.time.format.DateTimeParseException: Text '2012-02-22T02:06:58.147Z' could not be parsed at index 21

What is not right here?

Answer 1

The default parser can parse your input. So you don't need a custom formatter and

String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);

works as expected.
