Thanks, I looked at that and have a couple of questions.

As I understand it, org-encode-time is intended to be a compatibility 
function like org-newline-and-indent and org-string-distance. Those are 
in org-compat.el, so I assumed org-encode-time would be there too.

Also, if the intent is to emulate Emacs 29 encode-time, can't we do 
something like the attached instead? The idea is to implement Emacs 29 
encode-time both on pre-29 Emacs (that don't support lists of length 6) 
and post-29 Emacs (which might drop support for the obsolescent form).
