json.UpdateString("ntp_server","pool.ntp.org")

# Query the NTP server for the current date/time.
dt = Chilkat::CkDateTime.new()
success = dt.SetFromNtpServer(json.emit())
if (success == false)
    print dt.lastErrorText() + "\n";
    exit
end

# Show the date/time in various formats..
bLocalTime = true
print dt.getAsTimestamp(bLocalTime) + "\n";
print dt.getAsRfc822(bLocalTime) + "\n";
