So since getting my iPhone 5 on its release date this problem has come up a couple of times. First time, I was hiking at about 9 am and when I checked my phone to see the time it said 1030. This morning, I was almost late for work when my gf woke me up and asked me if I forgot to set my alarm for 6am. My phone said it was 1930 hours. I turn the phone off, and then back on the problem seems to self correct. As for the settings, I double checked. It is set to Set Automatically date and time. Anyone else having this problem?
