function chilkatExample() {

    var dt = new chilkat.CkDateTime();

    // Set dt to the current system date/time.
    dt.SetFromCurrentSystemTime();

    // Generate a ULID for the current UTC date/time.
    // (i.e. the current UTC UNIX-time)
    var utc = true;
    var ulid = dt.UlidGenerate(utc);
    console.log(ulid);

    // example result: 01GRGCH4J88RECEN4D4VK4F629

    // Generate a ULID using the local timezone's current time.
    utc = false;
    ulid = dt.UlidGenerate(utc);
    console.log(ulid);

    // 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.
    var dt2 = new chilkat.CkDateTime();
    utc = true;
    dt2.SetFromUnixTime(utc,1675609066);
    ulid = dt2.UlidGenerate(utc);
    console.log(ulid);
