Ah, the problem is that Windows is messing with your BIOS.  I boot my
laptop into Windows so rarely that just letting the NTP servers change
the time works (so it's a couple of seconds after I go to Windows that I
see local time correctly; likewise, it's a couple of seconds after I go
to Linux before my time is shown correctly).  Presumably you've got ntp
installed?

That said, it's supposed to be possible to fix Windows (all versions
since an early update to XP) to use UTC in the BIOS.  Here's a link to a
page giving instructions; like I said, I haven't bothered so this is
untested:
