Venezuela will move clocks in December, 2007... and you can test the change today in Windows
Navarrese Héctor, Minister of Science and Technology in Venezuela, announced that the "change to Venezuelan daylight saving time requires coordinations with diverse institutions and is what we are doing." (See this link on Windows Live Translator for an article.)
Translation: institutions such as banks need a little more time to make the change. The minister said that Venezuelans will move the clock back a half an hour from 12:00 on the night of the day it goes into effect, which they now project will be December 31, 2007.
As noted, Microsoft is supporting this change today with a hotfix for Windows in KB 938977. This update for the Windows operating system is available to allow customers and partners to test and implement the new time zone for Caracas, Venezuela, prior to the official move to the new time zone in the region. This update makes a change to your Windows operating system by installing a new time zone for Caracas, Venezuela. The name of the new time zone is Venezuela Standard Time, and the display name for this time zone is (GMT -04:30) Caracas.
Microsoft recommends that customers downloading this update should maintain their current time zone settings and confirm the start date of the time zone change in the Bolivarian Republic of Venezuela before using the new time zone. End users may install this update and the resulting new time zone may remain on the time zone with a display name of (GMT-04:00) La Paz, also known as SA Western Standard Time, until manually making a transition to Venezuela Standard Time.
Installing and using this new time zone prior to the official time zone change will impact the date and time on your computer (see below).
