spmug615 Updating Devices For Daylight Saving Q. My computer is set to adjust itself automatically for daylight saving time, but since the starting and ending dates for daylight time are changing this year, do I need to adjust my system clock manually? A. You can make manual adjustments, but if you use Mac OS X 10.3 and later - and keep your system current with all the latest updates, your computer has probably been fixed to reflect the new dates, including the start of daylight time this Sunday. Apple has its page of information for Mac at docs.info.apple.com/article.html?artnum=305056. Under the Energy Policy Act of 2005, daylight saving will begin three weeks earlier than previously and will continue for an extra week in the fall - until Nov. 4 this year. The National Institute of Standards and Technology has a page on the topic at tf.nist.gov/general/history.htm. Other programs and devices besides your computer's operating system may be affected by the change - for example, calendar software or hand-held organizers - so you should check with each manufacturer for updates. . Palm, another maker of hand-held organizers, has its information at www.palm.com/us/support/downloads/dst.html.
