So apparently Microsoft has released a patch for a bug in their software that may cause certain time functions to screw up when Spring '07 daylight savings is in effect.
Here is an excerpt from an email I received today:
In 2005, the United States government passed the Energy Policy Act of 2005. This act changes the start and end dates for Daylight Saving Time (DST) as of spring 2007. These changes may impact the way applications run. Microsoft is releasing an update for Windows through Microsoft Update that reflects these changes [...] Developers who use the .NET Framework may find their applications affected if the application uses the time zone information for historical purposes [...] In addition, developers who use Visual C++ may find their applications affected if they use the CRT time functions, or the TZ environment variable.
I love how is starts off by throwing the government under the bus. If this was passed in 2005, why are they releasing a last minute patch 2 years later? Apparently, they must have spent all their time cutting features out of Vista.
A patch for this is avaiable here: http://support.microsoft.com/kb/931836/ and more information can be found here: http://msdn2.microsoft.com/en-us/vstudio/bb264729.aspx
