Extract Timestamp from ULID

See more ULID/UUID Examples

Extract the date/time from a ULID.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final ulid = '01GRH14AA82EY9A7S99YYF2QDY';

  final dt = CkDateTime();

  // Unix timestamps stored in ULIDs should be UTC...
  final bLocal = false;
  // Set the CkDateTime from the timestamp contained in the ULID
  try {
    dt.setFromUlid(bLocal, ulid);
  } on ChilkatException {
    print('ULID was not valid.');
    return;
  }

  // You can now get the date/time in any desired format.
  // For example:
  print('Unix timestamp = ${dt.getAsUnixTime(bLocal)}');
  print('RFC822 = ${dt.getAsRfc822(bLocal)}');
  print('Timestamp = ${dt.getAsTimestamp(bLocal)}');

  // Sample output:

  // Unix timestamp = 1675608861
  // RFC822 = Sun, 05 Feb 2023 14:54:21 GMT
  // Timestamp = 2023-02-05T14:54:21Z
