Atomic Time
Freeware by Tom Wuttke

This is the simplest application that will synchronize your computer's
internal clock with that of an atomic clock on the internet.  If the time 
correction required is less than 30 minutes, it performs it without
asking.  Otherwise, it warns you in case your time zone or daylight saving 
time was incorrect.  Once it has synchronized the time, the program quits
so that it doesn't use any of your system resources.

It requires Win95 or WinNT, and you must have an active internet connection.

You only need one file, AtomicTime.exe.  Put it anywhere on your hard drive
and make an alias to it in your startup groups.  I include instructions when
you right click on the file and go to the properties/version info page. 

The thing that sets this program apart from the other ones like it is its
extreme simplicity.  It is only 40K, it is free, and you get source code.

The default time server is tycho.usno.navy.mil, but you can use any IP address
(check out their web page!)
