If you want to avoid a rude wake up call this Monday morning, 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.
Specifically, it 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.
