[pmwiki-users] Adding/subtracting days to ftime Page Text Variable

I tried and do my homework.
Although probably disgusting to well-trained coders, it seems that
such a bunch of lines

  MyDate:2007-01-02
  (:html:)
  <script>
  var date_changer = new Date("(:htmlend:){$:MyDate}(:html:)");
  date_changer.setDate(date_changer.getDate()-2);
  var my_new_date = new Date(date_changer).toISOString().slice(0, 10);
  document.write("MyNewDate:" + my_new_date);
  </script>
  (:htmlend:)

when placed on a html-enabled, password-protected wiki page, gives as
a result a new PageTextVariable that can be used as usual.

Thanks again!
