iPhone DST bug causing alarms to fail across Europe

The Web is full of reports that the iPhone alarms (for all models of device) going off an hour later than usual when switched between Daylight Savings Time and Standard Time. Later, we reported that firstly this problem was found out in Australia, now Europe faces with the same. So even though the iOS clock changed correctly over the weekend, the alarm is still locked to Daylight Savings Time. Apple acknowledged the bug with a promise to fix it with a software update.
