Microsoft distributes Microsoft SQL Server 2008 R2 Service Pack 1 (SP1) fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 R2 Service Pack 1 (SP1) fix release.
Symptoms
In Microsoft SQL Server 2008 R2 or in Microsoft SQL Server 2012, the daylight saving time (DST) for the United States begins at 02:00 on March 2 and ends at 02:00 on November 1. However, beginning in 2007, the DST for the United States was changed to the following:
-
DST begins at 02:00 on the second Sunday of March
-
DST ends at 02:00 on the first Sunday of November
In this situation, an incorrect value is stored in the TIME_ZONE column of the BACKUPSET table in the msdb database.
