    var ulid = "01GRH14AA82EY9A7S99YYF2QDY";

    var dt = new chilkat.CkDateTime();

    // Unix timestamps stored in ULIDs should be UTC...
    var bLocal = false;
    // Set the CkDateTime from the timestamp contained in the ULID
    var success = dt.SetFromUlid(bLocal,ulid);
    if (success == false) {
        console.log("ULID was not valid.");
        return;
    }

    // You can now get the date/time in any desired format.
    // For example:
    console.log("Unix timestamp = " + dt.GetAsUnixTime(bLocal));
    console.log("RFC822 = " + dt.GetAsRfc822(bLocal));
    console.log("Timestamp = " + dt.GetAsTimestamp(bLocal));

    // Sample output:

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