The AnimationEvent.elapsedTime read-only property is a float giving the amount of time the animation has been running, in seconds, when this event fired, excluding any time the animation was paused. For an "animationstart" event, elapsedTime is 0.0 unless there was a negative value for animation-delay, in which case the event will be fired with elapsedTime containing  (-1 * delay).


time = AnimationEvent.elapsedTime
