I believe that Linux box can be configured so that it treats the time
read from CMOS either as GMT or as local time (I have chosen local time);
If you choose the 'CMOS=local time' option during installation
and keep you clock up-to-date under DOS; both DOS and linux
should be happy.

Unfortunately, I have no idea how to set this option later
(i.e. not during installation)
