There is one advantage to using ntpdate_enable="YES" rather than ntpd_sync_on_start="YES" and that's the fact that ntpdate is blocking. When the rc script finishes you know the clock is correct, whereas with ntpd_sync_on_start the time step can be some time after the script has returned. If you run a daemon like dovecot that objects to time going backwards (and dies) that can be a problem. > --panicgate > > [2]: https://www.freebsd.org/cgi/man.cgi?query=ntpd > [1]: https://svnweb.freebsd.org/base?view=revision&revision=r326095 > > Author: manu <manu@FreeBSD.org> > Date: Wed Nov 22 15:27:47 2017 +0000 > > bsdinstall: Add ntpdate option > > When you install a computer for the first time, the date in the CMOS sometimes > not accurate and you need to ntpdate as ntpd will fail a the time difference > is too big. > Add an option in bsdinstall to enable ntpdate that will do that for us. > > Reviewed by: allanjude > Differential Revision: https://reviews.freebsd.org/D13149 > -- What do we want?
