start-timer

Arguments: timer &key interval

Starts timer, which must be an instance of the timer class, running. If interval is true, then the timer's interval property is first set to this value. An interval should be a positive integer indicating the number of milliseconds between successive firings of the timer.

If the timer is already active, it is stopped and then immediately restarted using its current interval. This differs from setting the active property to true, which starts the timer only if it is not already active.

See cg-timers.htm for more information on timers.
