DST 2007: December 2007 cumulative time zone update for Microsoft Windows operating systems

by Bharat Suneja

The last time we took a look at the timezone changes was when the August 2007 cumulative time zone update was released (Read previous post: “DST 2007: August 2007 Cumulative Timezone Update for Windows operating systems“). The August 2007 update included new timezone data for Caucasus Standard Time, Armenian Standard Time, New Zealand Standard Time, GTB Standard Time, and Jordan Standard Time. Some updates were minor – such as changing the display name of a time zone.

In December, Microsoft released another time zone update – KB 942763: December 2007 cumulative time zone update for Microsoft Windows operating systems. Changes:
Arabic Standard Time: Adjusts DST start and end dates for Baghdad time zone
Australia: Central Australia, Eastern Australia and Tasmania Standard Time – these start and end on the same day.
Egypt Standard Time: Adjusts DST start and end dates for Cairo time zone
Israel Standard Time: Adjusts DST start and end dates for Jerusalem
South America: E. South America Standard Time, Central Brazilian Standard Time – Adjusts DST start dates and end dates for the Brasilia time zone and for the Manaus time zone
Venezuela Standard Time: Adds a new time zone for the Caracas time zone

Updates in the above list reflect the latest time zone changes made around the world after the Aug. 2007 Cumulative Timezone Update was released. If you’ve already applied the previous updates affecting your locale, and rebased appointments, the latest update will not change anything for you.

Also note, this is a cumulative update. It includes all previous timezone updates.
