I think this is a simple case of misconfiguration and I suspect fiddling 
with it would just open up the possibility of more errors. If you say 
you are in a DST timezone and you don't check the DST checkbox, and you 
set the time to summer time then you're asking for trouble. I would not 
be at all surprised if the machine's idea of UTC was an hour out 
(Windows boxes keep the RTC on local time, not UTC, which is just horrid).
