Subject [jira] [Commented] (CASSANDRA-11137) JSON datetime formatting needs timezone
Date Wed, 27 Apr 2016 10:36:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15259946#comment-15259946

Stefania commented on CASSANDRA-11137:
--------------------------------------

I'm +1 on the dtest PR, assuming the test team is also OK with using ellipses to relax the
output checks.

We shouldn't backport a patch because of test limitations but, I've noticed that this ticket
is classified as a bug, so back-porting it might be the correct thing to do after all. Do
you agree that it should be back-ported to 2.2 and 3.0, [~iamaleksey] or [~slebresne]?

;
>  created_at
> ---------------------------

> {code}
> cqlsh:events> select created_at FROM event_by_user_timestamp ;
>  created_at
> --------------------------
>  2016-01-04 15:05:47+0000
> (1 rows)
> cqlsh:events>
> {code}
> To make things even more complicated the JSON timestamp is not returned in UTC.
> At the moment {{DateType}} picks this formatting string {{"yyyy-MM-dd HH:mm:ss.SSS"}}.
Shouldn't we somehow make this configurable by users or at a minimum add the timezone?
