    std::cout << dtTime.getAsRfc822(bLocalTime) << "\r\n";

    // Get as an RFC822 string in the local timezone.
    // (remember, the daylight savings that existed at the given time in the past is applied)
    bLocalTime = true;
    std::cout << dtTime.getAsRfc822(bLocalTime) << "\r\n";

    // Get as a 32-bit UNIX time (local or GMT..)
    // The Unix time is number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). 
    int unixTime = dtTime.GetAsUnixTime(bLocalTime);
    std::cout << "Unix time: " << unixTime << "\r\n";

    // One can also get the as a "DtObj" object for accessing the individual
    // parts of the date/time, such as month, day, year, hour, minute, etc.
    // The DtObj can be obtained in the GMT or local timezone:
    CkDtObj dtObj;
    dtTime.ToDtObj(bLocalTime,dtObj);

    if (dtTime.get_LastMethodSuccess() == false) {

        return;
    }

    std::cout << dtObj.get_Day() << "-" << dtObj.get_Month() << "-" << dtObj.get_Year() << " " << dtObj.get_Hour()
         << ":" << dtObj.get_Minute() << ":" << dtObj.get_Second() << "\r\n";
