You could use something like save-page-hook! if such a hook would
exist :) However, since there are no appropriate hook, you can
redefine the file save action(s). The attached script does just
that.

To load it automatically, place it in your ~/.gEDA and add the
following line in your ~/.gEDA/gschemrc:

  (load "moddate.scm")

This should work for 1.8.2 and later versions (though I didn't
test it for anything but the latest git version).

HTH,
  Vladimir
