When reading a parquet file which has timestamp fields they are read as a timestamp with timezone UTC if the parquet file was written by pyarrow 0.13.0 and/or 0.12.1.

Expected behavior would be that they are loaded as timestamps without any timezone information.

The attached files contain one row for all basic types and a few nested types, the timestamp fields are called datetime64 and datetime64_tz
