IPhone ALARMS 1 HR EARLY

I live in California, my time zone is set to "Cupertino", and Time Zone Support is on. I have a 3GS with iOS 4. This morning, my alarm went off an hour early. I have since done a little bit of testing & here's what I found:

A non-repeating alarm goes off at the corrrect time.

An alarm set to repeat "everyday" goes off an hour early.

An alarm set to repeat "every weekday" goes off at the correct time.

No idea what the cause is, but I hope that helps, anyway.

(It will be interesting to see what happens next weekend when we return to Standard Time!)

this has been happening to me and I live in Memphis, TN

My phone does the same and if you set the time manually (check the set time automaticly option to off ) then this problem is solved until apple comes out with a fix.

I agree that it's not DST specific but somehow I think it's a DST related issue, some glitch in the software.

This is what I posted in the other thread yesterday...

"I was late to update to iOS 4.1 but when I did the battery on my phone would drain at a drastic rate. I did a lot of things such as turning off push etc. to resolve this problem but to no avail.

This morning my phone alarm went off one hour early as some others have said. I live in North America so have not rolled the time back so this really doesn't explain the problem. After doing some online research I did a test on my phone and found that if the alarm is not set to repeat it goes off at the correct time, but if set to repeat (everyday) it will go off an hour early.

Furthermore my battery drain issue seems to be fixed as of today. I have used my phone very little today, as I have gotten used to using it sparingly, and my battery is still at 93%. In days recently passed with similar usage it would be down to 50% - 60%

Bottom line, something in the phone software (iOS 4.1) seems to have been set to change today 1 Nov. 2010 and apparently fixed a battery drain issue but screwed up the alarm."

I live in New York City. Same thing: starting yesterday, November 1st, iPhone alarm goes off one hour early if the alarm is set to repeat. Alarms that don't repeat go off at the time I've set them for. Silly, silly, silly.

If anyone gets an answer to this, post it. I'm having the same problem. My alarm set to go off each day started sounding an hour early on Nov 1.

I am in Ontario and have been having this problem as well. Why was it triggered November 1st? I hope they fix this soon. I use only my phone as my alarm clock!

Calgary Alberta Canada,
my alarm has gone off 1 hour early too, its pretty frustrating waking up at 5am instead of 6

It's 100% a DST related issue, it can't be coincidence that here in the UK we altered our clocks by exactly one hour at the same time this problem popped up.
As for a fix, maybe try turning of set date and time automatically or alter the calendar settings?

If you did a quick forum search you wouldn't need to speculate! There are numerous threads on this issue, complete with cause and cure.

I'm also in the UK and can't seem to work it out as it seems to be inconsistent as well - ladysun1969 posted that:

I have an "every weekday alarm" and its not going off at the correct time - I set it an hour early so that it would and that worked yesterday but not today :S

Will try Alienlove's advice and switch off automatic timezone off next.

Please apple - get us a fix soon!

My Iphone 4's alarm goes off an hour early for the last 3 days. I think, the problem will be ended when the daylight saving time start in the US. But for Apple, this is a major problem please fix the darn thing.

unfortunately the "cure" doesn't always work.

I did what was recommended by turning off "Set Automatically" and this morning I was STILL woken up an hour early!!!

After getting up one hour early the last few days I found a fix!

Go to Setting, Mail, Calender, Contacts and either turn off time zone support or make sure it is is the same time zone as your time setting. Seems like there are TWO time zone settings and that is the problem.

Dirk, I did not have success with this technique. My "time zone support" stays turned off. It was set to a different time zone (the time zone where my phone number is based) and even after setting it to the correct time zone I tested my alarms with repeat on for every day and it did not work properly. I even turned time zone support on with the correct time zone selected and it didn't work.

My findings thus far are that you can have the alarm set to repeat up to six days and it will go off on time (it does not matter which day you omit). But if you select to repeat everyday it will be an hour early.
