> Date and Duration data type classes are added to the staging branch of the protocol: https://github.com/data-apis/dataframe-api/blob/c5f08352e0a1d25387fe1737ffe9cccb36f554f7/spec/API_specification/dataframe_api/dtypes.py#L50 That's for the standard API, though, not for the interchange protocol (I was confused as well, and so wrote a wrong comment on the PR adding it asking for clarification ;) -> https://github.com/data-apis/dataframe-api/pull/197) > Yes, that was my idea. Similar to what polars does: https://github.com/pola-rs/polars/blob/2b43fc1ac1af84ed118ff3f8840d328a12c35510/py-polars/polars/interchange/utils.py#L35-L54 Personally I think it would be better if this was first clarified or added in the interchange protocol. While for date it does make some sense (as you could just see it as a different resolution of datetime), duration is really different. And for example the pandas implementation also wouldn't support consuming duration. And pyarrow only supports consuming datetime as timestamp, not even date. -- This is an automated message from the Apache Git Service.
