> Key: ARROW-1425
> URL: https://issues.apache.org/jira/browse/ARROW-1425
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Assignee: Heimir Thor Sverrisson
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.9.0
>
>
> 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.
