How to manually update the time zone definition in Windows SharePoint Services 3.0 and in Windows SharePoint Services 2.0 for the Venezuela time zone change

This article describes how to manually update the time zone definition in Microsoft Windows SharePoint Services 3.0 and in Windows SharePoint Services 2.0 for the Venezuela time zone change that begins on December 9, 2007. To do this, you must modify the Timezone.xml file and the Rgnlstng.xml file. Windows SharePoint Services uses the Timezone.xml and Rgnlstng.xml files to store time zone information and date and time information.

You must change the time zone definition file only if a region will change time zones. For example, assume that country Y is currently in the GMT-03:00 time zone. Country Y is changing to a new GMT-02:00 time zone. This change is scheduled to occur on a specific date, and there is no end date. In this example, you must change the existing time zone information for country Y.

Important We recommend that you apply the latest Windows SharePoint Services software update to resolve any issues with the Timezone.xml file. We recommend that you follow these steps only if you cannot apply the latest Windows SharePoint Services software update.
