Daylight Savings Time to change

Thanks to a new law, daylight saving time will start three weeks earlier and end one week later this year. It will begin at 2 a.m. on the Second Sunday in March and last until the first Sunday of November. And while the change is supposed to help save energy, it could wreak havoc on your computer. Experts say computers purchased before 2005 will most likely have to be manually adjusted. A common fix is called a patch, which will reprogram systems with the updated start and end dates for daylight savings time. Users of the new Windows Vista are immune, since Vista was finalized after the 2005 law passed. And computers running anything older than the most recent version of Windows XP, known as Service Pack 2, should simply go into the control panel and unclick the setting that tells the computer to automatically change the clock for daylight-saving time. And while experts say the daylight saving glitch will not be the Y2K frenzy of 1999, it could lead to some headaches if you're not prepared.
