Alarm won't go off

[shankun]

I use my phone as my alarm clock. I set it 10:45am, but it never goes off. When I wake up around 11:30 I grab the phone to see what time it is, the time will "flash" from 5:00am (example) to 11:30 then the alarm goes off. My phone is basically right out of the box. I reset it to the factory default and still does the same thing. Can anyone help me out with this? Maybe I am missing something here. I tried the alarm with manually setting the time and with having it get the time from the network.
