A Unix utility which, run by root as a cron job, calls the
National Institute of Standards and Technology in Boulder
Colorado in the U.S. and sets the system time from their bank
of atomic clocks. This was written for a Sun running SunOS.
Due to the variety of schemes for port locking, serial I/O
ioctls, etc. you may have some difficulty getting this to
work on your system. Note: if you're connected to the Internet, you don't
need this program; you can set your system's clock directly across
the net using the daytime
utilities available from the NIST.
