this has been totally maddening for me. i upgraded to ActiveSync 4.5 (taking the risk that Outlook 2000 might not sync, but fortunately it has synched). and I've run the other patches. but the Q still won't keep the correct time. I have changed it to the correct time manually but it keeps changing the time back an hour. I have tried the trick of changing to a different time zone and cycling on and off. But it keeps re-setting itself. AND it keeps changing the times of appointments on the Q.
