I do this by:

--8<---------------cut here---------------start------------->8---
#+NAME: mydateline
#+BEGIN_SRC emacs-lisp
(format "#+DATE: \\copyright{} %s\n" *this*) 

src_shell[:post mydateline() :results raw]{echo -n $(date +%Y) '@@latex:\\ 
\vspace*{0.1cm} \tiny \color{gray}@@' version $(git log --format=format:"%ad 
%h" --date=short | head -1 )} 
--8<---------------cut here---------------end--------------->8---
