             Summary: TimeZone.getTimeZone has performance issue.
                 Key: BEAM-552
                 URL: https://issues.apache.org/jira/browse/BEAM-552
             Project: Beam
          Issue Type: Bug
            Reporter: Satish Subhashrao Saley


While preparing Json response, we calculate the time zone for time related 
fields in response. Most of times user will not pass timezone. We can easily 
avoid TimeZone.getTimeZone for GMT timezone.
