Actions required: Daylight Saving Time (DST) information for IBM DB2® Everyplace®

Flash (Alert)


Abstract

In March 2007, the effective dates of DST in the U.S. and Canada has changed. DB2 Everyplace is affected by the changes in DST in 2007. You must take actions to address this issue if you are using DB2 Everyplace.

Content

The passage of the Energy Policy Act of 2005 alters the Daylight Saving Time (DST) start and stop dates by four weeks. Extended DST will begin in March of 2007. Beginning in 2007, DST start and end dates have changed to be:

    Start date: Second Sunday of March
    End date: First Sunday of November

As a result of this change, you must take actions if you are using IBM DB2 Everyplace.

Note that these actions apply only to the DST changes taking effect in March 2007 in the U.S., Canada, Bermuda and Bahamas. Information about the Energy Policy Act can be found on the US Department of Energy Web site.

Required actions
DB2 Everyplace Version 8.2 and its fix packs, and Version 9.1 are affected by the DST change because of the dependencies of the embedded DB2 products and the embedded WebSphere Application Server on the underlying operating system for time-related functions.

  • If you are using the separate DB2 Version 9 for Linux, UNIX, and Windows, or DB2 UDB Versions 7 and 8 instead of the embedded DB2 products of DB2 Everyplace, refer to the DB2 products DST change action plan.


  • If you are using one or both of the above embedded products, take appropriate actions as shown in the following table. The actions required depend on the version of the DB2 Everyplace product that you are using.

APPLY TO ALL VERSIONS: Ensure the operating systems on which these products are installed are DST compatible.
