Ok, found my script to jog memory on machine and 
then asked what others are using.

Common programs:

rdate
ntpdate
netdate

With rdate you just do

$ rdate -s tycho.usno.navy.mil
$ /sbin/clock -u -w

You must be root to do the clock setting.  I 
disabled my script as often times the navy.mil 
sites would not be accessible.  I have found that 
time.mit.edu seems to more readily accept 
connections for me and has proper time.
