Docs for that form: http://home.gna.org/guile-lib/doc/ref/debugging.time/

Also, as it turns out (of course I only knew this after I added time to
guile-lib), there is (ice-9 time):

;;; Commentary:

;; This module exports a single macro: `time'.
;; Usage: (time exp)
;;
;; Example:
;; guile> (time (sleep 3))
;; clock utime stime cutime cstime gctime
;; 3.01  0.00  0.00   0.00   0.00   0.00
;; 0

Andy
