#include <CkDateTime.h>

void ChilkatSample(void)
    {
    const char *ulid = "01GRH14AA82EY9A7S99YYF2QDY";

    CkDateTime dt;

    // Unix timestamps stored in ULIDs should be UTC...
    bool bLocal = false;
    // Set the CkDateTime from the timestamp contained in the ULID
    bool success = dt.SetFromUlid(bLocal,ulid);
    if (success == false) {
        std::cout << "ULID was not valid." << "\r\n";
        return;
    }

    // You can now get the date/time in any desired format.
    // For example:
    std::cout << "Unix timestamp = " << dt.GetAsUnixTime(bLocal) << "\r\n";
    std::cout << "RFC822 = " << dt.getAsRfc822(bLocal) << "\r\n";
    std::cout << "Timestamp = " << dt.getAsTimestamp(bLocal) << "\r\n";

    // Sample output:

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