-------------------------------------
That sounds inconsistent. Will have to take a closer look
> [Python] Creating a pyarrow.Array of date type from pandas causes error

> Key: ARROW-1718

> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Reporter: Bryan Cutler
> Fix For: 0.8.0
>
>
> When calling {Array.from_pandas} with a pandas.Series of dates and specifying
> the desired pyarrow type, an error occurs. If the type is not specified then
> {from_pandas} will interpret the data as a timestamp type.
> {code}
> import pandas as pd
> import pyarrow as pa
> import datetime
> arr = pa.array([datetime.date(2017, 10, 23)])
> c = pa.Column.from_array("d", arr)
> s = c.to_pandas()
> print(s)
> # 0 2017-10-23
> # Name: d, dtype: datetime64[ns]
> result = pa.Array.from_pandas(s, type=pa.date32())
> print(result)
