Description
A type of live region containing a numerical counter which indicates an amount of elapsed time from a start point, or the time remaining until an end point.
The text contents of the timer object indicate the current time measurement, and are updated as that amount changes. The timer value is not necessarily machine parsable, but authors SHOULD update the text contents at fixed intervals, except when the timer is paused or reaches an end-point.
Elements with the role timer have an implicit aria-live value of off.
Example
The timer role marks a region that contains a counter that represents either elapsed or remaining time that are updated as time changes until the timer is paused or completes the time count. A role of timer is a live region with an implied aria-live value of off.
