I did some searching but haven't seen any similar reports. On both my wife's 822 and mine, synced Calendar entries seem to randomly get moved forward an hour. For example, our shared room had an appt for 11am-noon. It's been there for a week. This morning I get up and it now shows as noon-1pm on both of our phones. On my wife's phone, another non-shared appointment also moved forward an hour but a different one did not.
