Hello I have a spring/jdbc/oracle 10g application. The Oracle server database timezone is set to GMT + 2 JVM timezone is GMT + 2 (even though it doesn't matter in my case). I have a stored procedure that performs some date operations. The problem is that session timezone is different(GMT) than database timezone even though I do not set session timezone explicit in my code/configuration. As far as I know the session timezone is by default equal to database timezone. Any idea why is the session timezone different than database timezone or how can I configure it in spring configuration (org.apache.commons.dbcp.BasicDataSource) ? Thank you.
