I noticed when daylight savings came in the phone had updated the time to an hour forward as it should. But this morning my alarm woke me an hour early at 5:15am instead of 6:15am. I checked the setting and it WAS set for 6:15am! Now yesterday I also updated from I think 4.0.1 to 4.1 so unsure if it was the daylight savings change or the update that has made my alarm change as this is the first working day since both.

So, any ideas or others with the same trouble?

    Can't help, but at can also confirm this has happened – iPhone 4 iOS 4.1.

    I guess we're just lucky this didn't occur when the clock went the other way

    Same thing here (4.1), I deleted all my saved alarm times and create new ones - alarms would only go off if set an hour early.

    Hi folks!

    Same issue here ... iPhone 4 on 4.1.

    Got a bit shock when my alarm went off at 5:50am instead of 6:50am ... I then deleted all alarms and created it fresh for 6:50am ... but it never went off.

    It seems if I set a one off alarm then it works fine - it goes off at the correct time.

    If I want to set a weekday alarm, then I need to set it one hour ahead ... e.g. to be woken up at 6:50am, I need to set it for 7:50am.

    Same here. I set my alarm at 6:20am everyday and this morning it was 1 hr early. and I noticed it is wrong. it should be 1 hr late if it is due by the daylight saving.

    Then, i noticed my alarm will only work if i set it as a one-off alarm instead of weekdays alarm.

    I tried different time, restarting.. deleting. nothing works!

    Its a software bug, plain and simple. The phone/ software uses a central clock. Each app takes its timing from this clock. When daylight saving kicks in the displayed time is adjusted appropriately. Same with the alarm. Apple developers apear to use some different software when you choose to have multiple days applied to the alarm. From a simplistic point of view it appears that in multiple day alarm mode it does not use the daylightsaving time it uses the phones real time clock. Either set the alarm 1 hour later or set an alarm for each day until the bug is fixed

    Same here on 3GS and iPod touch on 4.1, single alarms are fine, repeated alarms one hour early. Just glad I discovered it yesterday

    Me too. I suspect that this will affect New Zealand this week and Australia next week when each starts DST, so Apple support would have a much bigger surge of cases of this bug next Monday.

    The workaround of setting regular alarms for an hour later (NOT one-off alarms) is annoying but fairly simple, the worst bit may be being an hour late for work the morning after the fix goes in (assuming a fix comes before DST ends March/April 2011).

    I ran into a bug a lot like this in SGI IRIX years ago, in the "at" command. It only affected the Southern hemisphere where DST starts late one year and ends the next year. There was no symptom in the Northern hemisphere where DST starts and ends in the same year, where the OS developers/testers were.

    Same problem here. Really disappointed - I don't own an alarm clock, just have my phone.

    Yes, it would seem I was a victim of this problem too this morning.

    I have an alarm set for 6am weekdays but was woken at 5am with my alarm sounding 1 hour earlier than it should have. So, at 5am, I confirmed that my alarm was set for 6am, turned the alarm off / on and expected it to sound at the correct time but it did not. No alarm, breakfast, or shower this morning...

    Please sort this out Apple!

    Same issue for me this morning. iPhone updated itself to DST yesterday, but I had no need for an alarm yesterday. Regular week day alarm (that has been set since 2008) went off this morning at 0500 instead of 0600. New alarm set and returned to sleep only to wake up at 0715 as the new alarm did not go off.

    Have never had an issue with DST and the iPhone alarm until now... I guess setting a one off alarm would work,but is impractical. Hope that there will be a fix for this soon as I rely on the iPhone as an alarm clock (as well as for everything else in my life).

    I had the same problem as everyone else this morning, woken at 4am instead of 5am! One off alarms work OK. But repeat alarms need to be set for an hour ahead to work OK. Give it a try, it worked for me.At least its a temporary fix!
