ntpd not correcting system time, offset keeps increasing

[scar <scar%drigon.com@localhost>]

ntpd does not seem to be doing it's job.  i have Ver. 4.2.6p5 installed
on 6.1.5 and after 51 days of uptime, the system clock is 5 minutes
behind and the offset just keeps increasing.  ntpdate seems to work fine
when the system boots, but ntpd just isn't maintaining the time after boot.

here is my ntpd.conf:  http://pastebin.com/EbxzPBw7

i noticed /var/db/ntp.drift doesn't exist which sounds important to keep
the time maintained....

i used to have "restrict ntp.arizona.edu nomodify notrap" after the
server line at the end of the conf file but it sounds like those
settings prevent ntpd from working, so i removed it.  but after
restarting ntpd, the offset reported by ntpq just keeps increasing
