For those of you who aren't running Linux and are running Windows machines,
you might want to try grabbing the computer clock setting program from the
US NIST (National Institute of Standards and Technology).
The Internet-based one is at http://www.bldrdoc.gov/timefreq/service/nts.htm
The dial-up based (requires a modem call to Hawaii or Colorado) is at
http://www.bldrdoc.gov/timefreq/service/acts.htm
Both programs query the NIST time servers, and automatically adjust the
computer clock as necessary.
An anecdote: I attempted to set my computer clock just after 12:00 a.m. on
January 1, 2000, but to no avail. A TRACERT to the server showed me why--I
couldn't get closer than (apparently) the same city--the server was
overloaded with similar requests.
