Hi,
I had lots of problems with my clocks. Then I started to execute:
#hwclock --set --date="`rdate -p ben.cs.wisc.edu | cut -f 2`" --utc
#rdate -s ben.cs.wisc.edu
from my ip-up.local whenever I did dial-up. After about a week, my
hardware clock was stable. Now I rarely see any clock drift at all. I
believe that the adjtime is executed somewhere under rc.d (haven't
checked!) and that it's now slowly stabilizing.
Regards
Gustav
