Attention: Don't trust iPhone alarm clock during Daylight Savings Time changeover
The switch from Daylight Saving Time to Standard Time happens tonight at 2 am. But as we learned from Australian and and European iPhone users, the iPhone's alarm clock will not recognize this change. In fact, your alarm is likely to go off an hour late.
This is a very strange bug. Australian users were reporting that their alarms were going off early after the time change, and European iPhones were going of late. Even stranger is that we received reports of people in the US already being affected by the bug - their alarms are going off early.
The key thing to note about this bug is that it does not affect one-time alarms. So if you have a recurring alarm that wakes you up for work each morning, change the repeat interval to "never". It's very frustrating to need to set the alarm every day, but it's the only option until Apple releases a software fix.
The good news is, it is fixed in iOS 4.2 which might be coming as early as next week. The bad news is that's a week too late to help with this bug. I don't know about you, but I'm really disappointed in Apple for not releasing a quick fix for this bug. They knew about it, so they should've fixed it before the time change.

Don't set one for Mondays, one for Tuesdays, etc. Those are still recurring. Tue only alarm you can trust is one set for "never". You'll have to set a new alarm each day.
@jimi what, other than making sure their products work correctly, should Apple have to worry about?
If they had such a mechanism (which most OS's have), they could roll out patches much more easily to bugs like these.
Such a simple solution for all the hopla generated.
To everybody that has an ipad you'll be happy with iOS 4.2.

Strange though, at 11:00 AM PST the iPhone set itself at 12:00 noon back to DST setting. I discovered it while leaving church at 10:30 AM for lunch with friends. When I got to my destination, it was already 12:11 noon in my iPhone's clock. That place is only 30-45 mins (max).
As for those apologizing for Apple's flaw here, they can't have it both ways. Mr. Jobs argues repeatedly about how his products are superior. Therefore, Apple should expect the ire of it's customers when they fall beneath expectations - especially those with real world consequences for many people. They knew about this. They should have acted in a more timely way to correct the problem.
I think that will work. I just deleted my recurring alarm, and set up a brand new one (for a minute from the time I set it up) and it went off on time.
as per last night, I think this bug (Apple BUG ID# 8427270), is NO MORE a BUG any more...
What I mean is, either Apple send through iTunes - while iphone was on the dock - a silent update to iOS 4.1, or I fixed it by mistake, just bypassing an alarm...
What I mean is that I tried to make a repeat alarm firstly in the alarms list (eg. 07:00 Weekdays - I named it "work" but didn't make it valid (OFF))
Then (secondly) I made a repeat alarm (eg. 07:30 Weekdays, but do not name it!!! and make it valid (ON))
Try to do it and Test it, before you apply !!!
Mine is working, perfectly !
