iPhone hit by yet another daylight savings time alarm bug

Seems like Apple just can't get their alarms to work consistently following time changes. The bug struck again, according to BBC News, as some iPhone owners in the UK were late for work this morning after the clocks moved forward an hour for British Summer Time. Similar problems occurred during the switch to and from standard time in North America, and following New Year.

This time the glitch is not with the iPhone’s clock application but is affecting non-recurring alarms set within the iPhone's calendar application. The alarms either go off one hour late, or not at all. We are not quite sure why anyone would want to set up a morning wakeup call in this way in the first place, but the bug could also affect agenda alarms too.

I am in the UK and my alarm went off without a hitch today and all my agenda reminders too. Did any of our UK readers experience any alarm related problems this morning? Let us know in the comments!

iPhone hit by yet another daylight savings time alarm bug


Mine were fine, and I had a mix of recurring and non recurring set to go off.
All set through the clock application.

Same here, I've never had any issues with DST on iPhone 3GS or iPhone 4, and I set mine via the clock app on the iPhone.

Just check the days u want the alarm to go off and NOT auto recurring. Should be fine then.

Strangley mine worked fine this morning, but was affected by all the other alarm bugs thus far.
Im running 4.3.1

My wife uses her iPhone as an alarm clock. Her alarm that was set using the alarm clock app did not go off after we went to daylight savings time in the US this year. She was on iOS 4.3 at the time.
When daylight savings time ended last year I was in Arizona and my phone time changed (Arizona does not observe daylight savings time). I had to turn my phone off and on for it to reset to the correct time.
Apple really needs to fix the clock and alarm functions. Perhaps 4.3.1 does.

My phone was shut off this morning and took an extremely long time to turn on. My alarm (single use) was set to off when I know I turned it to on last night.
I'm in the USA, btw.

I think it would be good to get responders to put which version of iOS they are running? I have a sneaky suspicion that in iOS 4.2 which most JBers are still running the issue is still present and 4.3 has no problems. In my case, I'm in NA my iPad running 4.2 changed and then changed back so it was an hour off while my iPhone on 4.3 had no problems with the change and alarms.

This bug appeared in Sweden too! We went from winter time to summer time during the night from saterday to sunday, but still it didn't rang this morning. Really strange bug.

I'm in the US and my alarms didn't go off at all. I use Alarm Clock Pro Free, which has worked for me, even through the last bug. But I'm temporarily on a different iPhone 4 using iOS 4.1 anyway, so I imagine that's why.

I have no sympathy if people:

  1. Haven't upgraded to the latest iOS version
  2. Haven't already acted on past alarms... like deleting and re-creating perhaps.

Why should we have to recreate alarms to work around a bug Apple should have fixed long ago? The problem is still occurring on the latest firmware some people. Apple has screwed this up, not the consumers.
Anyway, this has affected my wife a few times already so now she relies on her clock radio to wake her up on time.

Mine has not been working!! I have to set my alarm an hour ahead LOL it really sucks!! If i put my alarm for 7:00am it will wake me at 6, so i set it @ 8:00 and it wakes me at 7.. very reliable i know...

I'm the U.S. by the way and even when I did the latest update, the alarm is still messed up, even when i sort it by days..

I need to set my alarm on iphone 3g to 6:00am in order to have the alarm go off at 5:00am. This all happened when we moved our clocks forward. Is there anything Apple is doing to correct this matter?

Apple gave away free bumper cases last time. So will Apple give out free alarms this time?

Relieved to hear (in the nicest of ways) that two others are having problems with being woken an hour earlier! Come on Apple, I'm running out of excuses in defending this bug thing :-(

I have the iphone 4. It really is awful, none of my friends have this problem with their iphone 4's except me, and I had NO issue in the fall when the clocks were changed an hour back, my alarm was NOT affected at all. what the hell apple!!

Am in UK, on iOS 4.3.1, synch with Outlook 2007, don't use alarms, BUT all repeating appointments have been changed incorrectly forward 1 hour (although they are correct in Outlook)! Correcting them in iPhone and resynching didn't alter the correct times in Outlook but a few duplicates appeared! Have Settings, Calendars, Time Zone Support set to London and Settings, General, Date 7 Time Set Automatically.

When sync your phone with MS Outlook, entries iPhone calendar appear one hour behind! So frustrated!

experiencing problems with iphone4 ios 5.0 daylight saving and outlook 2007
Have checked Laptop timezone and Iphone4 timezone concur (Time Zone Support = on), but still have the problem that all appointment alerts (synced from Laptop Outlook 2007) are happening 1 hour too early.
