    // If the SetFromNtpServer method is not present, contact support@chilkatsoft.com for a hotfix build.
    // It should be available in all programming languages/platforms starting in v9.5.0.97
    bool success = dt.SetFromNtpServer(json.emit());
    if (success == false) {
        std::cout << dt.lastErrorText() << "\r\n";
        return;
    }

    // Show the date/time in various formats..
    bool bLocalTime = true;
    std::cout << dt.getAsTimestamp(bLocalTime) << "\r\n";
    std::cout << dt.getAsRfc822(bLocalTime) << "\r\n";
    std::cout << dt.GetAsUnixTime(bLocalTime) << "\r\n";

    // Sample output:

    // 2023-10-31T09:43:27-05:00
    // Tue, 31 Oct 2023 09:43:27 -0500
