Daylight Savings Time (DST) will start in U.S.A from the 2nd Sunday of March and end on the 1st Sunday of November. This will impact the date and time rules of the operating system and JDK/JRE.
To make sure that log files contain the correct time in US time zones, and that Administration Server and Java Web Applications are not impacted by this change, do the following:
Download and use the appropriate operating system patches. You can download the Solaris patches from http://sunsolve.sun.com/search/document.do?assetkey=1-26-102775-1. For other platforms, download similar DST compatible patches from operating system vendor's web site.
Upgrade the JRE to make sure that Administration Server and Java Web Applications are not impacted by this change. Download and use the appropriate JRE that has the fix for DST changes. JRE versions for the supported platforms are as follows:
Solaris: 1.5.0_09 or later
Linux: 1.5.0_09 or later
HP-UX: 1.5.0.03 or later
Windows: 1.5.0_09 or later
