CMOS clock (was Re: BIOS clock problem) (fwd)

Ever since 1.3.x (0 <= x <= 35), my CMOS clock tends to loose ~4000
seconds per day when the machine is on, but it does not when the machine
is off. This behaviour seems to be related to the kernel updating the
CMOS clock while the system is running, but I can't see anything that
would cause different behaviour from 1.2.13 (which didn't munge the
clock). Perhaps some CMOS clocks are buggy when being updated? If
someone who is more familiar with the kernel's timing code could shed
some light on the subject, I'd be quite appreciative.
