If you work in just about any office environment, you've probably heard of the changes to daylight savings time by now. On top of causing massive headaches for people trying to organize changes in general, the new law could cause problems with computers, particularly with older software not written to handle DST like this. From customer equipment to computers to SANs, time synchronization is critical in a networked environment Active directory, for instance, will not let a user login if the time is skewed too far. NTP clients will panic and fail to update if their server is skewed too far. And, of course, there's the potential impact on scheduling.

DST already causes many problems every year, and this may be a particularly nasty one. IT staffs at businesses everywhere definitely have their work cut out for them.
