---------------------------------

             Summary: Hive Beeline should use timestamp in UTC
                 Key: HIVE-24618
                 URL: https://issues.apache.org/jira/browse/HIVE-24618
             Project: Hive
          Issue Type: Bug
          Components: Beeline
            Reporter: Kishen Das


Hive moved away from java.sql.Timestamp to java.time.LocalDateTime ( https://issues.apache.org/jira/browse/HIVE-12192, in order to be consistent w.r.t timestamp field irrespective of the current time zone. For example: for time zones like America/Los_Angeles that alternate between PST and PDT, time can be shown based on effective current time zone, which is set in the current SQL session. Hive Beeline should follow suit and use LocalDateTime ( A date-time without a time-zone ), when doing the conversion.  Also, it might be helpful if the user can set the user timezone in Beeline session, lets say "user.timezone”, which should be honored while showing the beeline output of a particular timestamp field. 

 

This issue is also more pronounced because of this bug in Java ->
