[b]Note:[/b] As it results from accumulating frame deltas, the time returned after the [Tween] has finished animating will be slightly greater than the actual [Tween] duration.

<description>
Returns [code]true[/code] if any [Tweener] has been added to the [Tween] and the [Tween] is valid. Useful when tweeners are added dynamically and the tween can end up empty. Killing an empty tween before it starts will prevent errors.
