1941775048,I_kwDOAMm_X85zvSLI,8302,Rust-based cftime Implementation for Python,57914115,open,0,,,2,2023-10-13T11:33:20Z,2023-10-22T16:35:50Z,,CONTRIBUTOR,,,,"### Is your feature request related to a problem?

I developped a rust based project with python bindings code to parse the CF time conventions and deal with datetime operations. 

You can find the project on GitHub at https://github.com/antscloud/cftime-rs.

It was something missing in the rust ecosystem to deal with NetCDF files, As the project in Rust hits its first working version, I wanted to explore the `maturin `ecosystem and the Rust as a backend for python code. 
I ended up creating a new `cftime ` implementation for python that have significant perfomance improvement (somewhere between 4 times to 20 times faster depending on the use case) over `cftime `original Cython code. 

There are surely missing features compared to `cftime`  and need to be tested more, but I think it could be interested as a replacement for some xarray operations (mainly for speed) regarding some of the issues of [topic-cftime](https://github.com/pydata/xarray/issues?q=is%3Aissue+is%3Aopen+label%3Atopic-cftime) label

Please, let me know if xarray team could be interested. If you are, I can open a pull request to see it is possible, where it breaks the unit tests and if it's worth it
