mroeschke opened a new issue, #49168: URL: https://github.com/apache/arrow/issues/49168
### Describe the enhancement requested In https://github.com/apache/arrow/pull/35656, it appears that `pa.Date32/64.to_pandas_dtype` was specified to return `datetime64[ms]` instead of `datetime[s]` because of a limitation in parquet(?) xref https://github.com/apache/arrow/pull/35656#issuecomment-1579572612 ```python In [1]: import pyarrow as pa In [2]: pa.__version__ Out[2]: '23.0.0' In [3]: pa.date64().to_pandas_dtype() Out[3]: dtype('<M8[ms]') In [4]: pa.date32().to_pandas_dtype() Out[4]: dtype('<M8[ms]') ``` I see that a `TIMESTAMP` with a `SECONDS` unit isn't still an official parquet type, https://parquet.apache.org/docs/file-format/types/logicaltypes/, but I was hoping that ideally this pandas conversion would ideally be de-coupled from this parquet limitation and return `datetime64[s]` for this API. ### Component(s) Python -- This is an automated message from the Apache Git Service.
