The alarm clock on the iPhone has been playing up after the phone switched to DST (Daylight Saving Time) in Europe. Thousands for people were shocked to find that their alarm had gone off an hour later, meaning that they were running late for going to work or taking the children to school.
We had assumed that just deleting the alarm times you had set and then redoing them would solve the problem – we were wrong. Apple has acknowledged that there is an issue and has confirmed that this bug will be fixed in the upcoming iOS 4.2 software update.
The easiest way to solve this issue for the moment is to set your alarm one-hour earlier. This issue has already occurred in Australia – so we knew it was coming. However, the U.S. will have to brace themselves for this alarm issue, so just make certain that you plan ahead – unlike me.
There is another solution to this problem, but seems to be a lot of hassle. Turn of automatic time zone adjustment, and then set the time on your iPhone manually. Then delete all alarms and then input them again, I have not tested this, but The Telegraph reports that this has worked for a number of iPhone users.
Why does iOS 4.1 have this issue, when past iPhone operating systems did not?
