Joris Van den Bossche created ARROW-5248: --------------------------------------------
Summary: [Python] support dateutil timezones Key: ARROW-5248 URL: https://issues.apache.org/jira/browse/ARROW-5248 Project: Apache Arrow Issue Type: Bug Components: Python Reporter: Joris Van den Bossche The {{dateutil}} packages also provides a set of timezone objects (https://dateutil.readthedocs.io/en/stable/tz.html) in addition to {{pytz}}. In pyarrow, we only support pytz timezones (and the stdlib datetime.timezone fixed offset): {code} In [2]: import dateutil.tz In [3]: import pyarrow as pa In [5]: pa.timestamp('us', dateutil.tz.gettz('Europe/Brussels')) ... ~/miniconda3/envs/dev37/lib/python3.7/site-packages/pyarrow/types.pxi in pyarrow.lib.tzinfo_to_string() ValueError: Unable to convert timezone `tzfile('/usr/share/zoneinfo/Europe/Brussels')` to string {code} But pandas also supports dateutil timezones. As a consequence, when having a pandas DataFrame that uses a dateutil timezone, you get an error when converting to an arrow table. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
