Daylight Savings Time and Windows
We have to change our clocks on Sunday here in the US, but if you're running a server, you need to know about this:
Sunday marks end of daylight savings time
October 27, 2006
[Folks across the country] can look forward to an extra hour of sleep as clocks turn back one hour in observance of daylight savings time at 2 a.m. Sunday morning.
The time shift occurs twice per year in North America: one hour is lost on the first Sunday in April, and the hour is gained back on the last Sunday in October. This policy was enacted by the Uniform Time Act in 1966.
Lawmakers made recent changes that will extend DST four to five weeks beginning in 2007. The Energy Policy Act of 2005 will change DST’s duration from the second Sunday of March to the first Sunday in November. Those in favor of the change said the US will save on energy costs by taking advantage of the extra hour of sunlight during the extended period.
It'll save on energy costs, but I wonder what the IT cost will be. Windows folks can check out http://www.microsoft.com/windows/timezone/dst2007.mspx for more details. Thanks to Tim Heuer and Bill Evjen for the pointers! A test version of the patch is available through support as KB924840.
From that page:
Windows XP SP2 and Windows Server 2003 will require the update. Windows XP SP1 and older operating system versions have passed their end of support dates and will not be receiving the update. Windows 2000 has passed the end of mainstream support and will not be receiving an update without an Extended Support Hotfix Agreement. Find more information about support policies around hotfixes.
So all you Windows 95, 98, ME, and 2000 folks, be prepared to be an hour off until you notice it and change it yourself. I predict 15 minutes until someone writes a freeware utility to fix this problem themselves. Will it be me? Nope, I'm taking Z to the Children's Museum.
