Github user weijietong commented on the issue: https://github.com/apache/drill/pull/904 @vvysotskyi has updated the mentioned parts. These [4ea36c3](https://github.com/apache/drill/commit/4ea36c3f18841b229aca5048b7d162ea16bfd5a1), [caa8b78](https://github.com/apache/drill/commit/caa8b78c5c31c44e59b5ff1bdf6f1900d14b1a1a) two links has been deeply thought about . I think they can't be solved using the same approach at current PR. They are too old to lost some function definitions like `casttimestamptz` . `VectorUtil.appendVectorAccessibleContent` 's date format does not retain time zone part. So I suggest they should be kept there or removed.
