Daylight savings change and alarm issue

I’ve contacted Apple about this bug. They have created a case for it and are looking into it.

You can also contact Apple if you like. The more people complaining about the issue will hopefully speed up the fix.

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

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.

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!

I read an article about this yesterday, and wanted to share it so you can read it if you'd like. I hope they get this fixed for you guys soon! The U.S. goes back to standard time in November, and I'm wondering if this bug will affect our phones. I guess we'll see!

So far I have tested this on my iphone 4 ios 4.1,
Using the clock app if I set an alarm with no repeats, it goes off on time.
If I set it to repeat even one day it goes off an hour early.

This occurs regardless if I have time set automatically or not.
And with restarts between.
I live in Auckland New Zealand, and have the time zone set to this.

I changed my time zone to Detroit (random city).
Turned off automatic setting.
Changed the date and time to my home town time.
Restarted.

And set an alarm, recurring, and it goes off fine!

Changed time zone back to Auckland,
Set time and date back to my current time.
restart.

And set an alarm, recurring, andit does not go.
So I set an alarm to an hour from now (with a minute to spare).
And it goes off an hour early.

It's an odd bug indeed.
And did just start with daylight savings.

This looks to be some weird line of code error that deals with alarms and DST.

Those who say they have not found this problem I would be keen to hear from you.
Have you set your home timezone, are you using the clock app for alarms.

My solution now is to set important alarms in calendar.
Though then my computer will no doubt give me alarms when I wake it at work (the one sync'd to my iphone).

Hi there

I’m sure most NZ’ers with IOS4.1 will be experiencing the issue as long as they have the device set to NZ times and the alarm is the repeat kind.

I've talked with apple and they can repeat the bug. It’s too early to expect Apple to announce that they are working on a fix but I’m sure that will happen soon.

At least we know they know so now you know they know (sorry for that)

Do use the email address from one of the threads above to email a bug feedback form to Apple. It’s easy to fill in. The more feedback they receive the more attention they will give to the bug.

I live in Queensland, Australia. My state does not observe daylight savings, but the rest of the east coast does. My iPhone 4 (4.1) alarm went off an hour earlier this morning (beginning of daylight savings). Time was correct, alarm was early, and after slide-to-stop, the alarm was still showing as set in Clock/Alarms. An iPhone 4 synced to a WinPC did not have this problem.

It was not a recurring alarm. Turning off Set Automatically in Date & Time seems to have solved the problem, but I would prefer Set Automatically working.
