I use a function like that here: https://github.com/jkitchin/jmax/blob/master/techela/techela-grade.el#L182
and to set the filetag as you suggest you would call it like this: #+BEGIN_SRC emacs-lisp (gb-set-filetag "DATE" (format-time-string "%b %d %Y, %a" (current-time))) #+END_SRC You could put that in some hook function if you like.
