Thanks to you and to François for pointing me to the right place.

I came up with this:

(defun ps-time-stamp-iso ()
  "Return date as \"2003-02-20\"."
  (format-time-string "%Y-%m-%d"))
(setq ps-right-header '("/pagenumberstring load" ps-time-stamp-iso ps-time-stamp-hh:mm:ss))

Is your solution preferable?
