Deja 2K All Over Again

Call it the law of unintended consequences. In 2005 Congress voted to extend daylight-saving time (DST) by four weeks, effective March 11, 2007. The purpose was to save energy by providing more usable daylight. But it also means a lot of wasted energy in the IT community, as administrators and programmers scramble to adjust the time on a host of computer systems that expect DST to occur on April 1.

Having your PC clock off by an hour isn't a big deal (unless you miss meetings), but the time change has become a hairy issue for banking, airline scheduling, freight tracking and industrial processes that rely on automated timekeeping. --Andrew Conry-Murray, [email protected]
