] | You can save the return value of `setInterval` in a variable to refer to it later - that way you can cancel it if you need to, or restart it.
See [this MDC article](https://developer.mozilla.org/en/window.setInterval) for more details.
The basics are:
```
intervalID = setInterval(flashText, 1000);
//do something...... | See:
```
var IntID = setTimer();
function setTimer(){
i = setInterval(startSlider, 4000);
return i;
}
function stopSlider() {
clearInterval(IntID);
}
//Restart Timer
// Option 1 make a restartSlider function and call it
$("#button").click(restartSlider);
function restartSlider(){
IntID = setTimer()... |

The interval part is here:

var int = setInterval($.fn.nextSlide, 3000);
$("#slideNavigation a").click(function() {
clearInterval(int);
setTimeout(function() {
setInterval($.fn.nextSlide, 3000);

});

If nothing is changing because in fact there is nothing there then it's right to say that no time is passing because there is nothing there including time.
If nothing is changing because everything is actually in stasis but could potentially change then time is passing.
