I've always had my BB's set to network time. My PC automatically adjusts its clock to a time server. Never had a problem and don't see how it could be a problem. If an appoiontment is listed in the BB and OL calendars at different times, that's one thing. If they are at the same time before sync and different after, that's a mystery to me.
