> The way that Spark treats non-timezone-aware timestamps as session local can
> be problematic when using pyarrow which may view the data coming from
> toPandas() as time zone naive (but with fields as though it were UTC, not
> session local). We should document carefully how to properly handle the data
> coming from Spark to avoid problems.
