    // Note: The SetFromNtpServer method is available starting in v9.5.0.96 for most Chilkat builds, but not all.
    // 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

    console.log(dt.GetAsTimestamp(bLocalTime));
    console.log(dt.GetAsRfc822(bLocalTime));
    console.log(dt.GetAsUnixTime(bLocalTime));

    // Sample output:

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