If you happen to power down your hp300 while you're off doing your
millennial partying, you will likely find that your system time
is screwed up when you turn the machine back on.  Specifically,
the kernel will whine about the date in the battery backed clock
being bad and will use whatever it finds in the superblock of
the root filesystem.  This will *not* occur if you leave the
machine on during the big tick, though your next reboot will load
the bbc with a decade value outside the specified range.  The
part appears to be willing to hold such a value in the steady
state.

I've just submitted pr 8824 which includes a patch for this in
case anyone cares.
