Of course, this is exactly the reason why you should run ntpd instead
of ntpdate on a cron job (especially a once-per-day cron job...)
I would again recommend clockspeed:

for machines which don't have continuous connection to the Internet
(where [x]ntpd won't do you any good). It handily reigns in bad clock
crystals with only a couple of external connections per month.
