spark.sql.datetime.java8API.enabledistrue, Spark dates and timestamps will be returned asjava.time.LocalDate/java.time.Instantrather thanjava.sql.Date/java.sql.Timestamp.https://issues.apache.org/jira/browse/SPARK-38437 addressed this in https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/util/DateTimeUtils.scala so perhaps this code path could leverage that?
