Running out of Time aka "Clock-Flew"
If you're running FreeBSD 5.2 on older hardware and find that the
system clock is gaining from 1-3 seconds per second, take a
look at the possible values for kern.timecounter.hardware. In
particular, I needed
kern.timecounter.hardware=TSC
to make one of my systems even vaguely synchronizable with ntpd, which
can only handle up to about a minute of drift a day. Obviously, 24*60
minutes of fast clock drift a day were way too much!
