If you want to avoid a rude wake up call this Monday morning — and possibly in Spring 2011 — here’s how to make sure your iPhone alarm doesn’t falter when daylight savings ends in North America on Sunday, November 7.
The snafu appears to be a problem with the synchronization — while the iPhone updates itself to recognize the daylight savings change in your time zone, it doesn’t update your alarm.
Because the bug has infected every device Apple makes that runs on the iOS4.1 operating system, that means your iPod touch (4th generation), iPod touch (3rd generation), iPhone 3G, iPhone 4, iPhone 3GS, iPod touch (2nd generation) could all set off the wrong alarm bells.
Specifically, the bug messes up repeating alarms set for anything other than “every day.” That means that your alarm will go off an hour late if you set it for “weekdays,” “weekends” or “every Monday,” for example.
Apple issued a support document for its top-selling smart phone just before the Northern America DST changes to stem the tide irate of jill-and-johnny-iPhone-come-latelys.
It advises iPhone users to “set the repeat interval to “Never.” You will need to reset these alarms for each day you need them. After November 7th, 2010, you can set your alarms to repeat again.”
That is — we expect — if you’ve checked that the alarm time has synchronized with the iPhone clock or you have manually reset it.
The iOS 4.1 bug should get the boot with the next software update, but Apple hasn’t announced when that will be ready.
The iPhone bug has already sent a ripple of “I Don’t Like Mondays” around the world from Australia to Europe as it either forgets to sound or goes off an hour late or an hour early.
Maybe if hits some key Cupertino employees, we’ll see a real fix sooner than later.
