|
|

|
|
;; This file implements two types of timers for Org buffers:
|
||
|
|
;;
|
||
|
|
;; - A relative timer that counts up (from 0 or a specified offset)
|
||
|
|
;; - A countdown timer that counts down from a specified time
|
||
|
|
;;
|
||
|
|
;; The relative and countdown timers differ in their entry points.
|
||
|
|
;; Use `org-timer' or `org-timer-start' to start the relative timer,
|
||
|
|
;; and `org-timer-set-timer' to start the countdown timer.
