func chilkatTest() {
    var ulid: String? = "01GRH14AA82EY9A7S99YYF2QDY"

    let dt = CkoDateTime()!

    // Unix timestamps stored in ULIDs should be UTC...
    var bLocal: Bool = false
    // Set the CkDateTime from the timestamp contained in the ULID
    var success: Bool = dt.setFromUlid(bLocal, ulid: ulid)
    if success == false {
        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
