Hi @sathyaprakashg This could be an API change and may cause performance regression for this operator. IMHO, we may need much stronger evidence to make the change, e.g. SQL standard, behaviors for `timestamp - timestamp` from other modern DBMS systems as much as possible. Otherwise, returning only micros part may be spark-specific but efficient and causes no ambiguity. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
