Getting Current Time on DB

To verify a bugs I had a need to get the current time on the Database
Server. Here are some SQL which might be useful.

Note: This is on Oracle DB

To get the server Date:

SELECT sysdate FROM dual;

This will give you the system date in this format, Ex: 18-AUG-09

To get the server TimeZone:

SELECT sessiontimezone FROM dual;

This will give you the system timezone in this format, Ex: Asia/Calcutta

To get the server time:

SELECT systimestamp FROM dual;

This will give you the system time in this format,
Ex: 18-AUG-09 04.49.43.648480000 AM -07:00
