yep 93b is a bit gross for no sane benefit.

May i suggest to go over just
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/touch.html
(the SUSv4 version) now that you essentially implemented about
everything anyway?

I'd put the susv4 stuff into the base applet and let the long version
of --time alone. It really feels useless, i never used it myself and
never saw any code or script that used it so far.

TIA,
