Just through adjtime away completely and fetch the time (ntpdate) when
booting. Run ntp on anything turned on more than a day if you care about
the time, run ntp *always* on networked computers that may run several
days at once.

I came to the same conclusion. I'd prefer to disable that
/etc/adjtime magic by default. It just leads to unexplainable clock
changes for those who don't know about the mechanism.
