             Summary: TIMESTAMP WITHOUT TIME ZONE
                 Key: HIVE-21349
                 URL: https://issues.apache.org/jira/browse/HIVE-21349
             Project: Hive
          Issue Type: Task
            Reporter: Zoltan Ivanfi


As specified in the [design doc for TIMESTAMP 
types|https://cwiki.apache.org/confluence/display/Hive/Different+TIMESTAMP+types],
 the TIMESTAMP WITHOUT TIME ZONE type shall behave like the LocalDateTime class 
of Java, i.e., each value is a recording of what can be seen on a calendar and 
a clock hanging on the wall, for example "1969-07-20 16:17:39". It can be 
decomposed into year, month, day, hour, minute and seconds fields, but with no 
time zone information available, it does not correspond to any specific point 
in time.

This behaviour is consistent with the SQL standard (revisions 2003 and higher).
