             Summary: JSON datetime formatting needs timezone
                 Key: CASSANDRA-11137
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11137
             Project: Cassandra
          Issue Type: Improvement
          Components: CQL
            Reporter: Stefania


The JSON date time string representation lacks the timezone information:

{code}
cqlsh:events> select toJson(created_at) AS created_at from 
event_by_patient_timestamp ;

 created_at
---------------------------
 "2016-01-04 16:05:47.123"

(1 rows)
{code}

vs.

{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?
