Here is one source (Windows only):
http://www.hiflite.com/nistclk7.html
This is what I use. It's not the best, but it comes from the horse's mouth (Windows & Mac):
http://www.boulder.nist.gov/timefreq/service/its.htm
A couple of points to note:
* This is not a high-accuracy service, technically speaking. For the highest accuracy, progams actually compute and account for network transmission delays to get to a few milliseconds accuracy. This will only set your clock to within 1 second (about 1/2 second - 500 milliseconds - in my experience) of NIST time.
* These programs (the 2nd link especially) generally offer an update interval. PLEASE choose something like every 12 or 24 hours! Otherwise the network congestion could cause NIST to withdraw the service! (Microsoft has a NIST widget with XP and they where forced to set up their own servers to prevent this. Apple may have done likewise since they have a widget in OS 8.5 and later)
Note for Mac users: The 2nd link above has a pdf document that has instructions for properly configuring a Mac to use it's own NIST widget, which is available in OS 8.5 and later.
