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.update("ntp_server", value: "pool.ntp.org")

    // Query the NTP server for the current date/time.
    let dt = CkoDateTime()!
    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
    // 1698745407
