RFC 868 time protocol is used mainly by UNIX systems, and some network devices, it uses port 37 over UDP or TCP. The BTT Software time server responds to both UDP and TCP requests on port 37. A list of recent requests is shown in the main window which can be used for debug / information purposes. Support has now been included for the System Tray. The server can also be run as a Windows 95 service using the .inf file provided. This version is the first release on CNET Download.com.
