crontabs have this handy '@reboot' syntax... It's all explained in
crontab(5).
However, you would be well advised to run ntpd(8) rather than bodging
the clock with ntpdate at intervals. ntpdate is deprecated by the ntp
project, given that ntpd now has the capability to synch the clock the
first time after restart no matter what the offset. Just add these
rc.conf settings:
ntpd_enable="YES"
ntpd_sync_on_start="YES"
Cheers,
