[jira] [Created] (CALCITE-3530) TIMESTAMPADD/TIMESTAMPDIFF with microsecond/nanosecond unit lost precision

Zhenghua Gao created CALCITE-3530:
-------------------------------------

             Summary: TIMESTAMPADD/TIMESTAMPDIFF with microsecond/nanosecond unit lost precision
                 Key: CALCITE-3530
                 URL: https://issues.apache.org/jira/browse/CALCITE-3530
             Project: Calcite
          Issue Type: Bug
          Components: core
            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.
