Subject [jira] [Created] (DERBY-6475) Update documentation for SYSTRIGGERS after DERBY-5866 changes
Date Mon, 10 Feb 2014 16:22:19 GMT
Knut Anders Hatlen created DERBY-6475:
-----------------------------------------

             Summary: Update documentation for SYSTRIGGERS after DERBY-5866 changes
                 Key: DERBY-6475
                 URL: https://issues.apache.org/jira/browse/DERBY-6475
             Project: Derby
          Issue Type: Improvement
          Components: Documentation
    Affects Versions: 10.11.0.0
            Reporter: Knut Anders Hatlen
            Priority: Minor


DERBY-5866 changed the meaning of the SYS.SYSTRIGGERS.CREATIONTIMESTAMP column.

Currently, the reference manual's mentioning of this columns says "Time the trigger was created".

I suggest we add something similar to:

"The time is stored in UTC if the trigger was created after upgrading to 10.11. Otherwise,
it is stored in the local time zone at the time the trigger was created. The primary purpose
of this column is to ensure the correct execution order of triggers, and the timestamp may
have been adjusted for that purpose, so applications should not rely on the accuracy of these
values."

Or maybe that's too much... "For internal use only" might suffice.
