Strange thing happened with time this morning

ok so I woke up this morning and thought it felt a little late. Looked at my iPhone and it said 8:26am - suitably freaked out but my alarm hadn't gone off either. I looked at our clock and it said 7:09am. Then I looked back at my phone and it said 7:09 and then my alarm which was set for 7am started going off.

I am having lots of problems with my iPhone and am heading to a knowledge centre next week so thought maybe it was just another problem.

This was until I saw a friend of mine post the same thing on Facebook and a few others had the same issue. Any ideas?
