Pausing a setinterval countdown?

Hi
I have built a Music Player on my site with a pause function. I have also put a setinterval to make the songs change when they are done. The problem I now realized was that the setinterval timer kept going when I paused the songs. How do I pause the setinterval and then resuming it?

Here is the code that I have on the frames:

function wait() {               
    nextFrame();
 stopAllSounds();
    clearInterval(myTimer);
}
myTimer = setInterval(wait, 208000);
s2 = new Sound();
s2.attachSound("i_have_you_to_thank");
i=1;
function timeme (){
now = new Date();
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds();
_root["nowtime"+i] = (Number(hours)*3600)+(Number(minutes)*60)+seconds;
_root.newstarttime = _root["nowtime"+i] - _root.nowtime1;
i++;
}
s2.start();
timeme();

Thank you all for the help

You will have to remove your interval (clearInterval) and then re-create it again when you want to start it again.
