import com.chilkatsoft.chilkat2.ChilkatException;
import com.chilkatsoft.chilkat2.DateTime;

public class ChilkatExample {

    public static void main(String[] args) {
        String ulid = "01GRH14AA82EY9A7S99YYF2QDY";

        DateTime dt = new DateTime();

        // Unix timestamps stored in ULIDs should be UTC...
        boolean bLocal = false;
        // Set the CkDateTime from the timestamp contained in the ULID
        try {
            dt.setFromUlid(bLocal, ulid);
        } catch (ChilkatException e) {
            System.out.println("ULID was not valid.");
            return;
        }

        // You can now get the date/time in any desired format.
        // For example:
        System.out.println("Unix timestamp = " + dt.getAsUnixTime(bLocal));
        System.out.println("RFC822 = " + dt.getAsRfc822(bLocal));
        System.out.println("Timestamp = " + dt.getAsTimestamp(bLocal));

        // Sample output:

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