;;; Commentary:

;; This code is meant as a demonstration of how to use the ZenIRC
;; hook mechanism and timer code to cause ZenIRC to do something at a
;; regular interval.

;;; Code:

(require 'zenirc)

(defvar zenirc-timestamp-interval '(0 600)
  "How often to insert timestamps into the ZenIRC buffer. The default
is 600 seconds or 10 minutes. The value of this variable is a 32 bit
integer, expressed as a list of two 16 bit values, ie, the default
value of 600 seconds is expressed as (0 600).")

(defvar zenirc-last-timestamp '(0 0)
  "The time the last timestamp was inserted into the ZenIRC buffer.
You shouldn't have to frob this yourself.")

(defun zenirc-timestamp (proc now)
  "Insert a timestamp into the the ZenIRC buffer specified by the
process PROC every zenirc-timestamp-interval seconds."
  (if (zenirc-time< zenirc-timestamp-interval
		    (zenirc-time-diff now zenirc-last-timestamp))
      (progn
	(zenirc-message proc (concat "[time] " (current-time-string) "\n"))
	(setq zenirc-last-timestamp now))))
