A bug in the iOS recurring alarm causes DST troubles in Europe
The same thing happened last month when Australia and New Zealand moved their clocks, but Apple didn't roll out an update. It will be interesting to see if they fix it by November 7th, when the whole of US does DST. The guy who has decided to introduce the adjustment Saturday against Sunday, has certainly been a clever one, as most users have caught their iPhone's shenanigans on Sunday. We can imagine the sort of havoc your phone's nonchalant behavior towards DST could bring on a weekday.
