This seems suspicious. What is the reason for inclusion?

[frenchy64]

Yeah I agree. Included it mainly to get tests passing and proceed without further distractions, no other reason. Was planning to have a second pass to cull unnecessary classes once the port is done.

Hi there, can I help in any shape of form here (maybe rebasing?)

I had again the though cause I was about to roll my own conversion functions that clojure.java-time has already, if only I could add it to my babashka-compatible project.

[borkdude]

There is one comment about the sun class which wasn't addressed.

I'm closing this as this PR looks a bit stale? Feel free to just provide smaller PRs that we can merge immediately. By now several java.time classes have been added, perhaps the PR isn't necessary anymore?
