IPhone users counting on the device to wake them this weekend got a surprise as the Apple Inc. gadget’s alarm-clock system failed for a third time.

A fault may prevent one-time alarms from working on Jan. 1 and 2, the Cupertino, California-based company said in a statement yesterday. Recurring alarms will still function on those dates and all alarms will operate from Jan. 3, according to Apple, which is the world’s third-most valuable publicly traded company.

Trudy Muller, a spokeswoman, declined to comment beyond the company’s statement.

A defect caused some iPhone alarm settings in Europe to go off an hour late on Nov. 1, failing to adjust automatically to the change as most countries in Europe switched to standard time from daylight savings. Similar problems affected iPhone users in Australia and New Zealand in September, causing their alarms to go off an hour early in the Southern Hemisphere, according to AppleInsider.com.

Apple shares climbed 53 percent in trading in 2010, following a 147 percent surge in 2009.

The stock closed at $322.56 on Dec. 31, giving the company a market value of $296 billion, making it the third most-valuable in the world. That’s behind only Irving, Texas-based Exxon Mobil Corp. and Beijing-based PetroChina Co., according to data compiled by Bloomberg.
