An alternate approach is to get the cheapest modem you can find, about $50,
and call the NBS's modem time phone when you want to reset the clock in your
computer.  A program to do so floated across comp.sources.misc a month or two
ago.  The cost is about 35 cents/call (a one minute call to Colorado), plus
your time porting the simple program that resets the clock.  At that rate,
you can make a lot of calls before you spend $250.
