I also am not bothered about running a time server, just really want it to sync on boot or every hour would be good enough.
You could create a cron job in root and have it run daily. Here's my cron entry. This runs every day at noon, to do this hourly change the 12 to a *.
00 12 * * * /usr/sbin/ntpdate -u -s -t 20 ntp.cpsc.ucalgary.ca....
It's not clear to me why you would want to do this when configuring ntpd is so easy -- just run redhat-config-date and check "enable network time protocol".
If you want time synchronization on a dial-up connection (where you aren't connected all the time), then there are ntp alternatives that do a good job for that: chrony (http://chrony.sunsite.dk/) for example. Just having npdate change the clock periodically isn't all that good -- note that ntp (and chrony, I expect) use adjtime(2) to speed up or slow down time to keep the clock adjusted.
