Arguments: timer
This function returns a positive integer indicating the number of milliseconds after a timer is started that it will "fire" by calling the generic function timer. The default timer method calls the timer's individual on-timer function (if it has one), which is where timer messages are usually handled by an application. If the interval property is modified while a timer is active, then the timer is stopped and immediately restarted using the new interval. The interval default-initarg for the timer class is 1000, which will fire the timer once a second.
Interval is a property of the timer class. setf may be used with
this function to change the interval for a timer.
