Description:
===========
In TIBCO BusinessEvents  using dbconcepts, how to ensure the timezone is not converted to local timezone when inserting a record into an Oracle database.

Environment:
===========
TIBCO BusinessEvents 5.x
All Operating Systems
Oracle Database

Symptoms:
=========
The "TIMESTAMP" fields reflect time using the local timezone rathen than the UTC timezone which is specified .

Cause:
======
If the dbtimezone is different from  the Java JVM timezone on the machine running the BusinessEvents engine, then the results would be coverted to dbtimezone.


Resolution:
========
1).Make sure the database timezone and Java JVM timezone are the same. The dbtimezone can be got from running the following query:

select DBTIMEZONE from dual;

2).To set the Java JVM timezone for TIBCO BusinessEvents runtime, add the following property to java.extended.properties in be-engine.tra file:

-Duser.timezone="xxx"

3).When running the  TIBCO BusinessEvents engine from Studio, you can pass -Duser.timezone="xxx" as a VM argument.
