Change in U.S. law requires updates

Due to a change in the law (The Energy Policy Act of 2005), Daylight Saving Time (DST) in the United States has been extended by four additional weeks. Starting in 2007, Daylight Saving Time begins on the second Sunday in March (March 11, 2007) and ends on the first Sunday in November (November 4, 2007).

If you use the QTIMZON system value, IBM has issued the following Program Temporary Fixes (PTFs) that add time zone descriptions to comply with the new rules for 2007 and beyond. After you apply the appropriate PTFs for your OS level, you can change the QTIMZON system value to the new value for your region. Note: Continue to check with IBM in the event that future PTFs become available.

• V5R4M0 PTFs SI26040 and SI25990
• V5R3M0 PTFs SI26039 and SI25991

Note: If your system uses a Hardware Management Console (HMC), you might need to apply additional fixes. If the HMC code is at version 6.1 or version 5.2.1, no additional fixes are required. Previous releases of the HMC code require additional fixes to support the changes in DST. Check with IBM for a list of PTFs that might apply to your HMC.
