Tardis is a shareware utility for Windows that makes sure your PC’s clock tells the right time. It can find out what the right time is in various ways including accessing Internet-based Atomic Clocks, using networked timeservers, GPS (The Global Positioning System), Radio clocks, and by listening for time broadcasts over a LAN.
The Service version of Tardis 2000 runs as a Windows NT/2000/XP/2003 "service", just like other services that come as standard with Windows.
The application version of Tardis 2000 does the same thing for Windows 95/98/ME/NT/2000/XP/2003. There is also a version for Win 3.x.
Both versions act as both a server and client for the supported protocols. I.e. they can get the time from a timeserver with the ‘correct’ time and then make the ‘correct’ time available to local clients.
