It's best to query several time servers and let ntpdate do it's thing.
If one server's time deviates too much from the others, it's ignored.
I saw a lot of systems get screwed up last year when theit time server jumped ahead 10 hours.

Try this:
[root at --- root]# crontab -l | grep ntp
30 1-23/4 * * * /usr/sbin/ntpdate -v -s -b -p 8 -u `cat /etc/ntp/ntp_servers`; 2>&1 > /dev/null ; /sbin/hwclock --systohc; 2>&1 >
/dev/null

[root at --- root]# cat /etc/ntp/ntp_servers
ntp-1.mcs.anl.gov ntp-0.cso.uiuc.edu ntp-2.mcs.anl.gov ntp-1.cso.uiuc.edu ntp-2.cso.uiuc.edu
