Bah. Should have known this would happen. Get pointed to the ntp site and
noticed documentation there covering ntpdate. Finally found out what all the
switches were (since I don't have a man page on my system).

ntpdate -u time.nist.gov
hwclock --systohc

-u forces ntpdate to use a port above 1024 to communicate with the timeserver
(useful since my systems are hidden behind a NAT router.
