Hi Esben,

I do it like that:

(defun my-insert-date (&optional arg)
  "Insert current date at point. With prefix arg, add that many days."
  (interactive "*P")
      (if arg
          (prefix-numeric-value arg)


> I'm using this to insert todays date: 
> ;;insert current date in ISO format,timestamp
>   (defun insert-date (prefix)
>     "Insert the current date. With prefix-argument, use ISO format. With
>    two prefix arguments, write out the day and month name."
>     (interactive "P")
>     (let ((format (cond
>      ;;              ((not prefix) "%d.%m.%Y")
>                    ((not prefix) "%Y-%m-%d")
>                    ((equal prefix '(4)) "%Y-%m-%d")
>                    ((equal prefix '(16)) "%A, %d. %B %Y")))
>           (system-time-locale "nb_NO"))
>       (insert (format-time-string format))))
