After change of daylight saving time all meetings one hour back!

Hi!
My computer was the only one in a windows 2003 server/exchange environment
that did not work well after change of DST.
All meetings inserted before 28th of nov changed one hour, to eg 0800 iso
0900. This applies also for reoccuring meetings.
If I today insert eg appointment 0800 for tomorrow, Outlook will show
correct, but then my Sony Ericsson P910i shows 0900! This is so strange.
The thing is that I do not want/dare to change all meetings one hour to
suddenly find that it has changed back because of a change in some settings.
Any idea?
