How do I get a reference to the timeslider of a map?

[stevemclaughlin]

How do I set the timestops of a timeSlider?
If I only have a reference to the map, how do I set the timestops of the associated timeslider?
EX: From the map, how do I get the timeslider?   Map.timeSlider returns a ITimeslider, not TimeSlider.
I need the TimeSlider so I can set the timestops on the TimeSlider.
thanks,

Steve,
it's ESRI developer team sample upgraded to show you the way to get a TimeSlider reference

Great, thanks!   just what I need
