With Daylight Saving Time (DST) set to end tonight there has been some discussion about what will happen next year when DST will start earlier and end later. As a long time reader of the RISKS Digest I can attest that there always seem to be problems with the timing (happening too early or too late in some part of the world) or with processes that are set to run around 2:00 a.m. that either don't run or run twice. I suspect that tonight will be no different. Microsoft has release information about how they plan to update current operating systems for the change in the US. According to the article at http://www.microsoft.com/windows/timezone/dst2007.mspx it sounds like they will release a single patch some time in the future that will update for the US and any other changes world wide.
And just in case you haven't been reminded/nagged enough, don't forget to change the batteries in your smoke detectors.
