writes "As I am sure some of you know, Daylight Saving Time is slated to change this year thanks to The Energy Policy Act of 2005. This means nothing to the large majority of the population except they will either sleep late one day or have to commute in the dark. To a select few, this is a crunch time akin to the y2k fiasco, only there has been almost zero publicity recently. These select few are the ones responsible for updating the millions of computers, both servers and workstations, with the new time zone information. For newer servers, this usually means just install a patch and reboot (which is slightly more than mildly inconvenient). For older servers, this is basically an "End of Life" declaration. Servers running software for which no patch is available will be unable to update their own clocks. This doesn't seem like such a big deal until you realize Microsoft is only offering patches for WindowsXP and newer and Sun is not supporting Solaris 7 and older. That should knock a large percentage of the computers 1 hour off for a few weeks this spring. What are you doing in your datacenter to prepare?"
