I have an issue the the Alarm clock on the Pre. I have set up an alarm that recurs daily on weekdays at 6:45 am. Lately an odd thing has been happening. On day it will go off on time but the next day the alarm will change the time to 5:45 or 4:45 am. I often notice that alarm makes this adjustment sometime mid day and if I remember I can go in and reset it. Has anyone else exerienced this or have any insight?
