Everyone can stop time, if they die. Time is a series of bubbles, each an ever-expanding wave. The wave is the effect that it has on our perception of Time itself. The Earth is a Time wave which we have divided into measurable intervals called hours, minutes, seconds. But how is it a bubble if it is only ratating on its axis? Hour 24 is a different location in space than hour 1 was. The Earth is actually spiraling, not rotating.
You can stop your own Time but you cannot stop the time for everyone else because the main Time waves are impossible to stop. They are the Earth's rotation, the Sun's rotation, the Galaxy's rotation and the mother Time bubble, the Universe.
