At the time the function was introduced, the docstring clearly said:
"The number of options reflects the strftime(3) function."

http://cvs.savannah.gnu.org/viewvc/emacs/emacs/src/editfns.c?r1=1.67&r2=1.68&pathrev=HEAD

Two years later Richard rewrote the docstring and that bit disappeared:

http://cvs.savannah.gnu.org/viewvc/emacs/emacs/src/editfns.c?r1=1.153&r2=1.154&pathrev=HEAD

It is open to interpretation (or asking him) whether the intent was to
detach strftime from format-time-string or not.
