Trying in /etc/rc.conf

ntpd_enable="YES"      
ntpd_sync_on_start="YES"

resulted in
Starting ntpd.
Jul  7 16:31:47 nemesis ntpd[1736]: leapsecond file ('/var/db/ntpd.leap-seconds.list'): expired 10 days ago
which looks like UTC presented as PDT.

Trying in /etc/rc.conf
ntpd_enable="YES"            # Run ntpd Network Time Protocol (or NO).
ntpd_sync_on_start="NO"     # Sync time on ntpd startup, even if offset is high
ntpd_flags="-q"
resulted in a report ending 
 7 Jul 16:37:55 ntpd[1731]: Clock offset exceeds panic threshold.
 7 Jul 16:37:55 ntpd[1731]: Set system clock by hand.

Finally, adding ntpd_sync_on_start="YES" set the time sensibly during boot.

Thanks very much, ntpd is now usable!
