Thanks for replying.
If I change the TimeZone I can only move to a couple of hours forward or backward. I want to create a DST environment. For that I have to move to Sunday March 11, 2012 2:00:00 AM, and November 4, 2012 2:00:00 AM
Please tell me how I can change my server timings or trick JVM by moving to the above mentioned timings.
