             Summary: timestamp_add(UNIT, DATE) should return timestamp if the 
unit added is less than a date
                 Key: CALCITE-1312
                 URL: https://issues.apache.org/jira/browse/CALCITE-1312
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: MinJi Kim
            Assignee: Julian Hyde


timestamp_add("MINUTE", 1, date '2016-06-15') returns 2016-06-15 since it 
returns a date and therefore truncates the minute informtion.  timestamp_add 
should return timestamp instead of date for units less than date.
