> Timestamps in the future (year 2250?) and before ~1700 are silently corrupted in vectorized execution mode. Simple repro:
> {code}
> hive> DROP TABLE IF EXISTS test;
> hive> CREATE TABLE test(ts TIMESTAMP) STORED AS ORC;
> hive> INSERT INTO TABLE test VALUES ('9999-12-31 23:59:59');
> hive> SET hive.vectorized.execution.enabled = false;
> hive> SELECT MAX(ts) FROM test;
> 9999-12-31 23:59:59
> hive> SET hive.vectorized.execution.enabled = true;
> hive> SELECT MAX(ts) FROM test;
> 1816-03-30 05:56:07.066277376
> {code}
