I haven't had that, but ever since Daylight Savings time was over my Calendar alerts have been going off an hour before they are supposed to and also 20 minutes before they are supposed to. For example, I set an event for 4:05 and an alert for 5 minutes before, so it should go off at 4:00, right? But it goes off at 3:00 and the event shows up as 3:05 on the initial turn-on screen but when I go into the Calendar it shows up as the original 4:05. And an alert goes off at 3:40 as well! Has anyone else seen this? Or have a fix for this?
