--------------------------------------
Summary: [Python] Pandas roundtrip doesn't preserve list of
datetime objects
Key: ARROW-3448
URL: https://issues.apache.org/jira/browse/ARROW-3448
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Krisztian Szucs
Adding the following to the pandas_example.py::dataframe_with_lists functionn:
{code:python}
datetime_data = [
[datetime(2015, 1, 5, 12, 0, 0), datetime(2020, 8, 22, 10, 5, 0)],
[datetime(2024, 5, 5, 5, 49, 1), datetime(2015, 12, 24, 22, 10, 17)],
[datetime(1996, 4, 30, 2, 38, 11)],
None,
[datetime(1987, 1, 27, 8, 21, 59)]
]
type = pa.timestamp('s'|'ms'|'us'|'ns')
{code}
breaks the tests cases, because the roundtrip doesn't preserve the object type.
