Problem with Syncing with PC

[Speedy64i]

After installing vista or the Clean and simple AKU3.5 rom to my pocketpc I now have a problem with syncing my device. Everything appears to be normal but al tasks and some appointments that i make on my pocketpc show up on my PC as the previous day. For example if i make an appointment for April 4th on my pocketpc, it will show up as due for April 3rd on my PC. The alarm reminder will also be set for April 5th on the PC where it was originally set for the 4th on the pocketpc!

So weird and annoying! If anybody has any ideas to try it would be greatly appreciated.

Thanks,

JT
