> Key: ARROW-5889
> URL: https://issues.apache.org/jira/browse/ARROW-5889
> Project: Apache Arrow
> Issue Type: Bug
> Affects Versions: 0.14.0

> Priority: Minor
> Fix For: 0.14.1

> 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
