Tween class question

hi
i have several elements that have tweened animations, all of them starting at the same time. one last element should start the tweening some moments later. is it a way to start the animation after a specified time??? i don’t want to user the timer class. i read the reference and all the methods and of properties of the tween class and none is useful to me. i just want a method to tell the tween to start at a specified time. is there a way to do this in a simple way?
thanks for your help
