Yes, as Paul mentioned NTP is easy to use.  I installed it
from an RPM (in the contrib section of Red Hat's site) and
sync it to my provider every time the IP link comes up.
(My provider seems to be only one hop from one of the
Japanese standard sites.)  The other machines on my home
LAN sync to the gateway machine.

Actually, GPS isn't too expensive nowadays.  I bought the Delorme
Tripmate package which includes mapping software (only for the US)
and a small GPS receiver on the end of a 9 pin serial cable.  It
is going for US$149.  I get a constant stream of time (and position :-)
information at 9600 baud.
