LOL, I just noticed that. I am in Arizona where we don't believe in Daylight Savings Time, but my iPad2 thinks we do (I hadn't noticed that the setting changed when I switched to the 3G version). Not too much of a problem, but I had my alarm set for 9am so it woke me up an hour ago, at what was actually 8am. I am dumbfounded that it took me this long to notice.
But I could have sworn it was too early for 9am when I got up. I was still quite tired... Oh well, not as bad as if were fall and I need to be some where in the morning and it woke me up an hour late.
