Re: [BUG] incorrect result with C-c ! to correct (complete) a date [9.7-pre (release_9.6.1-306-ga645a6 @ /home/d/src/git-org-mode/lisp/)]

Do `C-h v org-read-date-force-compatible-dates` and read the doc
string of the variable.  You can customize the variable and set it to
`nil' which will give you a much wider range of dates to choose from
*assuming that your Emacs is compiled for and runs on a system that
can deal with such dates* (this is related to the "2038" problem[1]  where
32-bit (signed) timestamps will not be enough to count the number of seconds
since the "beginning of time" (that's 1970-01-01 at least as far as
Unix is concerned :-)) 

This is a difficult compatibility problem which is being worked on on
many fronts and I think there have been discussions about it on this
list.

But read the doc string, experiment on your system and see if you can
live with the consequences of choosing the "other" value for the
variable.
