Hi Shubham,

Can you be more specific what you are trying to do? You can stop and start animation time by clicking the play/pause button on the Animation Widget (#6 on the image below).

![Cesium Viewer](https://cesiumjs.org/tutorials/Cesium-Workshop/images/viewerAnnotated.jpg)

You can do the same by setting [Clock.shouldAnimate](https://cesiumjs.org/Cesium/Build/Documentation/Clock.html#shouldAnimate).

viewer.clock.shouldAnimate = true; //play  
viewer.clock.shouldAnimate = false; //pause

``

Thanks,

Gabby
