Attention iPhone users;

use a standby alarm clock for now

If you live in the United States, you're probably already aware that the nation is set to switch to Standard Time on November 7, moving clocks one hour back. What you may not be aware of is that if you're using an iPhone or other iOS device as your primary alarm clock, it might not make the switch as planned -- and you could end up late to work on Monday as a result.

apple has posted a support doc on its iOS DST issues, and the company recommends changing repeating iOS alarms in the Clock app to single-use alarms instead as a way of skirting the issue, but it has the added inconvenience of having to remember to set the alarm every day.

Bottom line: if you're worried about being late to work on Monday, or losing an hour of sleep, the best advice we can give you is to use a different alarm other than your iPhone or iPod touch for now. While the issue is reportedly resolved in the forthcoming iOS 4.2 update, that update is unlikely to be publicly released before the changeover to Standard Time this Sunday -- so if you're on thin ice at work already, don't depend on your iPhone to wake you up on Monday morning.

The daylight savings time is coming to the US on Sunday 7 November, so if you want to avoid having trouble with your alarms, you have two options: either you buy a standard alarm clock for your bedside table, or you use any of the dozen alarm apps you can find in the App Store.
