Symptoms



Possible reasons to follow this note:

* The result of SYSDATE and SYSTIMESTAMP is not what is expected and is one (or several) hours "off".
* The result of SYSDATE and SYSTIMESTAMP of a "local" oracle_sid connection using sqlplus on the server shows the correct time but when using sqlplus with an remote (listener) connection SYSDATE and SYSTIMESTAMP are not correct / one or more hours "off".

 For changing the result of SYSDATE and SYSTIMESTAMP to a NEW timezone please see <note 1988586.1> How to Change the "Database Time" ( SYSDATE and SYSTIMESTAMP) To An Other Time / Timezone
