Three years later, I finally tried this:

I made it read a time interactively:

    (defun as-org-todo-time-machine (arg)
      (interactive "P")
      (let ((fake-time
             (apply #'encode-time (org-parse-time-string
                                   (org-read-date)
                                   ))))
        (cl-letf (((symbol-function 'current-time)
                   (lambda () fake-time)))
          (call-interactively #'org-todo))))

It almost works perfectly, although monkey-patching current-time doesn't affect
the code in org-auto-repeat-maybe which sets LAST_REPEAT, since that uses
the built-in format-time-string:

    (org-entry-put nil "LAST_REPEAT" (format-time-string
      (org-time-stamp-format t t))))

I found that adding (current-time) as the optional time parameter fixed it:

    (org-entry-put nil "LAST_REPEAT" (format-time-string
      (org-time-stamp-format t t)
      (current-time))))

since that allows the monkey-patching to apply there too.  Is it worth
submitting
a patch for this?
