  OK, rc.conf(5) does the trick.

  Look here for an overview of rc.conf:

  And try the next command to gather information about rc.conf(5):
  man 5 rc.conf

  Possibly you are looking for the /ntpd_program/ variable (from the
manual page):
		 (str) Path to ntpd(8) (default /usr/sbin/ntpd).

  Bad practice... ;)

  No problem, just try the configuration above. Also, you do not need
to restart the complete system, just proceed as follows:

1. As root stop ntpd:
  # /etc/rc.d/ntpd stop

2. Edit the /etc/rc.conf file...

3. Start ntpd:
  # /etc/rc.d/ntpd start
