The last time I checked on Windows, it expected to have the internal
(BIOS) clock in the computer set to local time. Admittedly, I can't
remember when I last checked, perhaps some time late last century. If
Windows people have recently improved their system to make it capable
of handling UTC, good for them. I think I am not alone in being unaware
of recent twists and turns in Windows.
If you are trying to have both Windows and Debian runable on the same
computer, you need (purely as a convenience) to have them both set up
to expect the same setting of the BIOS clock. The UNIX world settled
on UTC for the BIOS clock many years ago, long before Debian existed.
Since you report that Windows can now be set to use UTC time, I think
you should switch the Windows setting to UTC and the BIOS clock
setting to UTC, and finally verify that Debian GNU/Linux (UNIX) is
still set to its default clock convention.
