and those whose responses may be in the mail.
Almost everyone pointed me to NTP/XNTP; some suggested using rdate. As
the immediate solution I chose Sanjiv K. Bhatia solution and made the
system crontab:
05 04 * * 6 /usr/ucb/rdate india.colorado.edu > /dev/null 2>&1
I also downloaded xntp3-5.91.tar.gz from http://www.eecis.udel.edu/~ntp/
to install later.

Subject: RE: Time synchronization
Joe,
The easy way is to use the rdate command to get the time of a time
keeping site, such as the US Naval Observatory, on a regular basis. This
can be put into the system crontab file to run daily, e.g.,
30 23 * * * rdate tock.usno.navy.mil > /dev/null 2>&1
If you have a standalone system this works fine. If you have a network
of Suns, you can designate one as a master to sync to the USNO as above,
and then periodically run rdate on each of them to synch to the master.
The harder way is to use ntp (Network Time Protocol) to allow continuous
synching of clocks. This is also good if you have a mix of Sun, HP-UX, or
other UNIX boxes.
The source code for this is available from:
http://www.eecis.udel.edu/~ntp/
Good Luck,
Marc L. Herbert
