From ntpd(8):
     -s          Set the time immediately at startup if the local clock is off

                 by more than 180 seconds.  Allows for a large time correc-

                 tion, eliminating the need to run rdate(8) before starting

                 ntpd.
Or is that not what you meant?
Just put ntpd_flags="-s" into /etc/rc.conf.local.
