Description

In IMPALA-4363, we decided not to validate the time component of timestamp because it was not clear how to handle leap seconds. This means that currently timestamps read from a Parquet file can look like:

1995-01-01 54:34:17

We need to learn more about the behavior of such timestamp values and figure out if they might cause a crash.
