    // To generate a ULID using a specific UNIX timestamp

    // For example, the Unix timestamp for Sun, 05 Feb 2023 14:57:46 GMT
    // is 1675609066

    // For more information about the Epoch Unix Timestamp, see Epoch Unix Timestamp

    // To generate a ULID from a specified date/time, set the CkDateTime and then generate the ULID.
