I thought the answer was so obvious I didn't respond... here's an example:
(defvar *dumped-lisp-time* (get-universal-time))
(defun conditional-lisp-restore-fns ()
(unless (and (< (- (get-universal-time) *dumped-lisp-time*)
3600) ;; less than an hour old..
(not (y-or-n-p "Pretty fresh lisp. Call restore-fns anyway?")))
Assuming the time is set correctly on the machine.
The window could be made smaller, and you could also test for time zone,
"current" time before dumped time, etc.
