[jira] [Updated] (ARROW-378) Python: Respect timezone on conversion
of Pandas datetime columns

> -----------------------------------------------------------------

> Key: ARROW-378
> URL: https://issues.apache.org/jira/browse/ARROW-378
> Project: Apache Arrow
> Issue Type: Bug

> Currently we convert columns irrespectively of their timezone directly to timestamps in Arrow. While in Pandas you are able to specify timezones, in Arrow we have the assumptions that a Timestamp is always the time of the specified unit since 00:00:00.000 on 1 January 1970, UTC. Thus we have to check if {{df['column‘].tz}} is set and convert if necessary to UTC before converting to an Arrow column.
