Coming December 11th to an Internet connection near you: the 2008 Cumulative Daylight Saving Time and Time Zone update for Windows OSes.  And yes, Venezuela is part of this update.  This update is now available for IT Pros and SysAdmins as a download from Microsoft KB Article 942763.

Generally, end users do not have to install these updates manually, as updates like this one will be installed automagically via Windows Update beginning on December 11, 2007 rather than download and install these from the Microsoft Download Centre (as noted in the KB article link above).  For end users who have their PCs managed by a central administrator, please contact your IT administrator for information on how PCs on your network will be updated. 

More about Venezuela. Typically, the government of the Bolivarian Republic of Venezuela has observed South America Western Standard Time. According to current official reports, the start date for new time zone is yet to be determined, but reported to occur on December 9th, 2007.

When customers move their Windows clients to the new time zone, clocks will move backwards 30 minutes, from UTC -4:00 to UTC -4:30. This change begins at 2:59:59 PM local time on the start date. Clocks should be moved back to 2:30:00 PM rather than advancing to 3:00:00 AM. For more information, please see Microsoft KB article 942763 for the Windows Cumulative Update.
