The suggestion to add %s was made by Konrad Schwarz in an email
reply to the aardvark:

https://www.opengroup.org/austin/mailarchives/ag-review/msg02839.html

As far as I can see from the mail archives there was no discussion of it.

If we do add %s to date, we should consider whether (for consistency)
to add it to strftime() and strptime() as well.  Although it would
be kind-of redundant for those functions (being equivalent to
mktime() and localtime() respectively, plus conversion to/from a
string) I can see an argument for adding it so that it can be used in
user-supplied/configured format strings.
