Spring Ahead, Fall Back; Repeat

Spring ahead, fall back. And fall back again, for many whose clocks wrongly reset themselves last weekend—1 week ahead of the schedule Congress set when it extended Daylight Saving Time. Most cell phones and computers, which get time and date information from networks, weren't affected, but many alarm clocks and PDAs that predated 2005 jumped the gun, MarketWatch reports.

"Some of the PDAs are going to have problems, but most of the bigger manufacturers got their software ironed out," said one tech expert. Nevertheless, users, including those with BlackBerrys and Palm Pilots, should check manufacturers' websites for software updates. And for those facing a biannual annoyance? Most devices should allow you to disable the time-change feature. (More daylight saving time stories.)
