  Linux doesn't tie the system time to the hardware clock the way
Windows/DOS does.  The system will use the hardware clock at boot, of
course, but if something sets the system time in Linux (e.g., with the
date(1) command), that doesn't automatically set the hardware clock,
too.  One of the things the shutdown scripts (are supposed to) do is
use the system time to set the hardware clock, with hwclock(8).  You
can also run hwclock manually, at the command line, to query/set the
hardware clock.  I'd start testing there.
