Ensure you due ntpdate before you run ntpd.
This can be done just once from the command line and ntpd cannot be running.
ntpdate ntp2.sf-bay.org
then add the following to /etc/rc.conf
ntpd_enable="YES"
ntpd_flags="-c /etc/ntp.conf -p /var/run/ntpd.pid"
between the lines is a example of ntp.conf in /etc
====
#List of servers to pull time from
server ntp2.sf-bay.org
server clock.isc.org
server clock.via.net
server ntp.ucsd.edu
#This is created automaticaly you do not have to touch it
#However it might take hours for it to be created
driftfile /var/db/ntp.drift
#This Line restricts which hosts are allowed to pull from your box
restrict 172.30.0.0 mask 255.255.0.0 notrust nomodify notrap

restart your box
check ntp using ntpdc
$ ntpdc -s
