If the clock gets set backwards, you ought to see the effect in the
logs (messages) because MARK is added every twenty minutes.
If you shutdown *without* letting "etc/init.d/hwclock.sh stop"
execute (temporarily move the link first), is the RTC still correct?
If so, that puts paid to a battery fault.
Is the clock perhaps just freezing while the machine sleeps? I think
you have to have a daemon running which resets the clock when it
wakes up, but I don't know the details. Perhaps it doesn't run correctly.
