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 maturinecosystem 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 cftimeoriginal 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 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
