If You Have An iPhone and Depend on a Recurring Weekday Alarm Then Remember This Tip For the Daylight Savings Time Change This Weekend

Due to a glitch in the iPhone's operating system, any iPhone user in the United States (in a state with DST) may not wake up to their alarm on Monday morning as it will not ring on time.

Apple is now suggesting users delete and then reset their phone's alarm clock after November 7 as the phone's alarm app does not recognize the time change. The clocks go back one hour in most parts of the United States and Canada at 2am on Sunday November 7.

Users are being asked to create 'one-time alarms' for Monday morning according to Apple spokeswoman Natalie Harrison.

"We suggest customers set nonrepeating alarms for now and reset after November 7 to resolve the issue," she told CNN.

Later this month, Apple will release an updated version of its mobile software, iOS 4.2, which will permanently fix the problem, Harrison said.

Apple became aware of this problem after iPhone users in Australia and Europe reported that their alarms did not go off on time.

If you're in the United States and want to create an iPhone alarm that will work Monday, follow these steps:

1. Open the Clock application.

2. Click on the Alarm icon at the bottom of the screen.

3. Click the "plus sign" icon in the top right corner.

4. Create an alarm and make sure you have the "repeat" option set to "never." (The glitch only occurs with repeat alarms, such as those workers set to wake them up at the same time each weekday).

5. Select the appropriate time and sound, and click "save."

6. After November 7, you can again create repeat alarms without trouble, but you should delete any recurring alarms that you set before that date, Harrison said.
