The man page also says, by default, if the clock is in error more than 0.5
second it will step, rather than slew, the time.
What I see as a problem is in /etc/rc.network where it pipes the output of
ntpdate to /dev/null. If ntpdate fails to step the clock, and the clock
is way out of sync, then ntpd (if enabled) will also fail to work.
/etc/rc.network should be smarter and check return codes when starting
ntpdate and/or ntpd. Should it pipe the output to logger(1)??
