Dan, something I've always wondered about: if a machine runs ntpd during
normal operation and is rebooted mainly for periodic maintenance, wouldn't
it's hardware clock be accurate to within a few fractions of a second during
the downtime? I mean, if my clock it NTP-correct at noon, and I reboot the
machine to do a `make installworld', it will be pretty close to accurate
when I bring it back online. Since ntpd launches instantly when not in `-q'
mode, what's the advantage or point of running ntpdate on boot? Why not
just start ntpd as normal and let it smooth over the small amount of drift?
