Marios Trivyzas commented on FLINK-24421:
-----------------------------------------
We checked with calcite-avatica's
[https://github.com/apache/calcite-avatica/blob/master/core/src/main/java/org/apache/calcite/avatica/util/DateTimeUtils.java]
file where the relevant code was copied from into the `SqlDateTimeUtils` and
we decided to keep the behaviour as is to be in sync with calcite.
Moreover there was a fix in avatica:
[https://github.com/apache/calcite-avatica/commit/cac2ffaaf97572d21cba195d7590d9ab0d32382e]
which is not ported to `SqkDateTimeUtils` currently but will soon open the PR
to do so.
