iPhone Alarm Bug during Daylight Savings Time

[Xenedis]

This week I discovered an annoying problem with the alarm clock built into the iPhone.

Last night I had the alarm set to 6:50pm, but it went off one hour earlier.

This afternoon I tried setting it for a specified time, and discovered it didn't go off at the specified time.

I looked around the Web, and found a discussion about the problem (http://forums.vogue.com.au/showthread.php?t=367211).

There seems to be a bug triggered by daylight savings time taking effect.

One post on a forum suggested setting the timezone to Vladivostok, Russia (GMT +11), but I tried this to no avail.

Another post indicated that the problem occurs with recurring alarms. If the alarm is set to a one-off occurrence, it signals at the correct time. When I tried this, the alarm went off when it was supposed to do so.

Until Apple fixes the bug, users have two options, both of which are non-optimal:


set recurring alarms to one hour later; or
set one-off alarms every time.

Hopefully this advice will help those who have been bitten by the bug, or who will eventually be bitten by the bug, with disastrous consequences.

Mine is fine. I have lots of appointments etc set in my iPhone and its been working on the right time. No probs at all

I'm not sure if the bug affects notifications of calendar events, but it does affect the alarm clock when the alarm has a recurrence.

AH ok. my confusion. I don't use the alarm clock at all.

Who you with?

Those with Optus got a carrier software update before DS kicked in.

I don't think the issue is carrier-centric.

My iPhone has the correct time.
