Module talk:Date table sorting

This is an initial attempt at translating Template:Dts and Template:Dtsa to Lua. This was a request made here: Wikipedia:Lua/To_do#Templates_to_be_converted

we had a hackaton, I wanted to learn Lua templates while perhaps being useful, this proved to be fun enough to go back and improve bit by bit..

Any comment will be welcome.

A few questions for this module:

1. dtsa - should the template mimic the dtsa template, or dts with abbr=true? The latter is both more consistent and easier to program.
2. The original request mentioned subpages of dts AFAIU there are just used to build dts. Meaning - once I "pass" dts - I don't need to try and understand/replace the subpages. Am I right?
3. I assume template-"&nbsp" and " " are identical, and ignore other similar whitespace differences. I consider the current module to pass all tests even though these tests fail. Any comments on that?
4. Parsing a date that was entered as a single parameter is one of the largest problems. The Template:Dts documentation says any date parsed by php is legal, and [php documentation] offers endless, sometimes conflicting, options. I found a semi-logical approach that handles all the examples from Template:Dts, re-using most code from date input as separate parameters. Php offers many more formats, and I would like to understand if all are important, and if not which are.
