Daylight Savings Time (DST) starts in USA from the 2nd Sunday of March and ends on the 1st Sunday of November. This impacts the date and time rules of the Operating System.
To make sure that the log files contain the correct time in US time zones, and that the Administration Server is not impacted by this change, Sun recommends you to do the following:
Download and install 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 the respective Operating System vendor's web sites.
For Solaris, Windows, and Linux, run proxy server with JRE 1.4.2_13. For HP-UX, run proxy server with JRE 1.4.2.12.
