Anyone noticed problems with calendar items scheduled prior to the 19th of March when NZ daylight savings end?

All my meetings scheduled prior to the 19th are out by 1 hour i.e. i'd schedule a meeting for 09:00 - 10:00 and it stays like that on my desktop calendar whilst it moves on 1 hour on my PDA2K soon as I synch with the Exchange server.

Other people have the same problem using SmartPhone 3
