Hi Eric,

yes and thanks for the previous help, too.. the good old printf.. I would like to pass the result of time() directly to a lisp function, like:
#+TBLFM: $6='(coolfunc (time(...$5)-time(...$4)))

If I would know how to pass the result, eg as a string, to a lisp function I could sort it out, I guess.

Thanks,
Martin
