func chilkatTest() {
    // Specify the NTP server domain.
    // Information is passed in a JSON object to allow for any unanticipated future optional information that might need to be provided.
    let json = CkoJsonObject()
    json.UpdateString("ntp_server", value: "pool.ntp.org")

    // Query the NTP server for the current date/time.
    let dt = CkoDateTime()
    // 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
    var success: Bool = dt.SetFromNtpServer(json.Emit())
    if success == false {
        print("\(dt.LastErrorText)")
        return
    }

    // Show the date/time in various formats..
    var bLocalTime: Bool = true
    print("\(dt.GetAsTimestamp(bLocalTime))")
    print("\(dt.GetAsRfc822(bLocalTime))")
    print("\(dt.GetAsUnixTime(bLocalTime))")

    // Sample output:

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