In one of the Oracle database server it is showing "+01:00" when I fire the "Select dbtimezone from dual" does that mean in summer the clock will shift one hour ahead ?. In another server it is showing "+00:00" does that mean the database server setting is GMT ? but I am using the sysdate in oracle pl/sql. Client is saying the Aix server is on DST so would that mean the DB server will adopt the AIX server setting after clock change ? How to fix this problem.
I resolved this issue by using the below command "Select Systimestamp at time zone 'GMT' from DUAL' This command wil always give the GMT date and time irrespective of OS time.
