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

             Summary: TIMESTAMPADD/TIMESTAMPDIFF with microsecond/nanosecond unit lost precision
                 Key: FLINK-14889
                 URL: https://issues.apache.org/jira/browse/FLINK-14889
             Project: Flink
          Issue Type: Bug
            Reporter: Zhenghua Gao


Since the TimestampAddConvertlet and TimestampDiffConvertlet tread TIMESTAMP as long (with millisecond precision), they lost precision even if the downstream can support microsecond or nanosecond.
