We just started Daylight Savings Time in New Zealand yesterday. Since then, many iOS users here have experienced what's probably one of the weirdest bugs I've ever seen: our alarms are now going off an hour early. My iPhone's alarm woke me up at 5:50 in the morning today instead of 6:50, and it turns out I'm not the only one.
In the iPhone's built-in Clock app, setting a recurring alarm will cause it to trigger an hour early every time if you're running iOS 4.1, iTunes 10.0.1, and live in a Southern Hemisphere country that's just gone over to Daylight Savings Time (which, for now at least, just means New Zealand).
