I wanted to fire up a function every hour to get the weather from the web. I first tried `run-at-time' but could not get it to accept any time specifications. e.g. (run-at-time "11:23pm" 3600 'test-func) I then switched to an itimer and found what I believe is an inconsistency with decode/encode-time. `decode-time' produces a list of three (3) integers but `encode-time' only produces a list of two (2) integers. Is this the correct behavior? It makes it hard to use `itimer-time-difference'. Example: (let* ((now (current-time)) (time (decode-time now)) (go (encode-time 0 10 (1+ (car (cdr (cdr time)))) (car (cdr (cdr (cdr time)))) (car (cdr (cdr (cdr (cdr time))))) (car (cdr (cdr (cdr (cdr (cdr time)))))) ))) (itimer-time-difference go now) ;; fails: ;; Wrong type argument: number-char-or-marker-p, nil I believe the first problem is related to the second since timer.el uses encode/decode-time and also returns `Wrong type argument: number-char-or-marker-p, nil'. Hope this mumble makes sense to someone. Sean -- Sean MacLennan Just crank that volume to the point of pain.
