Daylight Saving Time Problem
Interesting topic for daylight saving time problem in oracle database. Many of DBA's thinking for daylight saving time changes database timestamp changes require.
Just wants to share you all. Daylight saving time is related to application setup not database related. If your using > oracle 9i no changes require from database level.
As per my understanding there might be some EMC tool available for daylight saving time changes for application or operating system.
