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).

For more information about how to manually change your time zone, please see the following:

Your questions: Why did parts of Indiana just move to the Eastern time zone?

“I saw that several Indiana counties will move from the Central time zone to Eastern time. When did this happen?”

This was announced yesterday by the DOT, as noted in this article…

“The U.S. Department of Transportation announced Thursday a final rule moving five Indiana countries — Daviess, Dubois, Knox, Martin and Pike — from the Central to Eastern time zone. The five counties, which filed a joint petition for the time zone change, will observe Eastern time beginning Nov. 4, when daylight saving time ends.

“At the same time, the Department denied a separate petition from Perry County to also move from the Central to Eastern time zone.

“With the change, 80 of Indiana’s 92 counties and more than 5 million of the state’s 6.2 million citizens will observe Eastern Time.”

Venezuela announces a delay in their time zone move… again

And you thought it was a slow news day on the time zone front…


Yes, more on Venezuela’s new time zone.

First it was announced that Venezuela would change their time zone by 30 minutes, by turning their clocks back on January 1, 2008… then September 17… and more recently September 24th.

Now Reuters reports today that there’s been confusion in Venezuela with the announced time change… so much so that the government officials behind the change aren’t sure whether to spring forward or fall back.


President Hugo Chavez wants Venezuelan clocks turned back half an hour and he wants it done in record time — next Monday.

“I don’t care if they call me crazy, the new time will go ahead, let them call me whatever they want,” Chavez said on his weekly TV show. “I’m not to blame. I received a recommendation and said I liked the idea.”

Chavez himself has not had time to get to grips with the practicalities of the clock shift.

In his live show, he talked with his brother, the education minister, so that the two men could explain the measure. But they mistakenly told Venezuelans to move their clocks forward at midnight on Sunday, when the policy is to move them back.


Wait: that’s not all.

We have reports tonight that the government may delay the half-hour move all together until October (see this link and translation ) as they…


“… need to notify the international organizations such as the Bureau the International of Weights and Measures and the Bureau the International of the Measurement of the Time, located in France.



“It will take at least two to three weeks for the change to take shape. The President of the Republic (Hugo Chavez) will make the official announcement of when [people] will have to move their clocks by half an hour…

“The change of the time zone of Venezuela will take shape within two or three weeks… according to vice-minister of Planning of the Ministry of the Popular Power for Science and Tecnología, Luis Marcano González.”


We are confirming this with our offices in the region.

For now, we are holding the down level hotfix packages, as noted in KB 938977 which has been held back for the moment. As soon as we receive approval from our offices in the region, we will repost the KB and the packages will be available.

Update: The KB is now live and you can request the hotfix by going to http://support.microsoft.com/gp/CUHotFix_LandingPage_Request.
