SNTPClock

Download

SNTPClock is a NTP time server monitor that polls a NTP server using the SNTP protocol (basically NTP without the synchronisation behaviour). I wrote it after having some problems with the NTP service on a server I was using.

FEATURES

  • Written entirely in C++ using MFC
  • User specified time server to monitor
    • By hostname
    • By IP address
  • Displays clock information and statistics
    • UTC time
    • Local time
    • Time zone information
    • Analogue clock faces
    • Digital clock display
    • NTP source's reported precision
    • Stratum of selected NTP source
    • Selected NTP source's higher stratum source
    • NTP protocol version and mode
    • Polling latency
    • LED style stability monitor
    • Worst measured clock drift

NB: UNDER NO CIRCUMSTANCES should you use SNTPClock to monitor a time server you don't own or one where the operator has not specifically authorised your use of SNTPClock. In particular, you should NOT use SNTPClock to monitor Internet NTP time sources. Monitoring them isn't necessary and you WILL get your IP address blocked by the server's operator. SNTPClock polls NTP servers faster than once per second but will not damage a NTP server.

When the stability monitor goes red you can reset it by right clicking on it and selecting reset from the context menu. I'm still working on the installer, right now it puts all files in the Windows directory. This isn't as bad as it sounds, all but one of the files is a shared DLL anyway. The one file that isn't (the application itself) is a diagnostic utility that you may wish to start without using the start menu.

REQUIREMENTS

SNTPClock will work on any 32 bit version of Windows that has a network connection that can be used to access a NTP time source.
