 create table employee (eid INT, birth timestamp) stored as parquet;
 
-- The parquet file was written with Hive 3.1.3 using the new Date/Time APIs (legacy=false) to
-- convert from US/Pacific to UTC. The presence of writer.time.zone in the metadata of the file
-- allow us to infer that new Date/Time APIS should be used for the conversion. The
-- hive.parquet.timestamp.legacy.conversion.enabled property shouldn't be taken into account in this
-- case.
