Hi
the real problem is to find the correct time stamp even in entries
that have multiple time stamps, just as Nick is saying.
Your best bet will indeed be to write a custom sorting function
for ?f, because the way this function has to be written depends
on how your entries look.
For example, if we assume that the creation time is the first
inactive time stamp that is at the beginning of a line (to exclude
things like a CLOSED time stamp), you could use
(defun sort-by-creation-time ()
(let ((end (save-excursion (outline-next-heading) (point))))
(if (re-search-forward (concat "^[ \t]*\\[" org-ts-regexp1 "\\]")
end t)
(time-to-seconds (org-time-string-to-time (match-string 0)))
(time-to-seconds now))))
