It's UTC.  Having the hardare clock in UTC is normal and standard.

The basic problem is that Windows keeps the hardware clock in
localtime but modern systems keep the hardware clock in UTC.  They are
fundamentally incompatible.

You can configure Debian's /etc/default/rcS to keep the hardware clock
in local time too.  (With UTC=no)  But if you only dual boot very
rarely then I wouldn't do it.  I would simply live with Windows having
messed up time.  It should be fine when you boot Debian.

It is fine when you boot Debian, right?  If not then install 'ntp' and
it will be fine.

Windows is just /displaying/ the clock as localtime, not setting the
clock, right?  That is what I see when I dual boot a machine.

By the way...  The date on your email is UTC.  Is that also your local
time zone too?
