I'm not aware of any built-in support for this.

I think this is the easiest approach, though I'm not sure such a wrapper
needs to live in Org proper. Here's a snippet from a recent thread [*]
that should get you most of the way there:
(defun my-org-todo-time-machine ()
(interactive)
(cl-letf (((symbol-function 'current-time)
(lambda ()
(apply #'encode-time (org-parse-time-string
"2019-11-27 Mi 16:44")))))
(call-interactively #'org-todo)))
