I'm working on Timer of hrs seconds minutes. I use setInterval for start it.
but when click on button to restart the timer it doesn't work again.
The button suppose to clear the timer ( clearInterval ), then restart it again.

I Tried calling the function which contains the timer after clearInterval but timer still doesn't work.

Timer Code 

```
function gameTimer(intervalTime){
    var input = {
        hours: 0,
        minutes: 0,
        seconds: 0
    };

    var timestamp = new Date(input.hours, input.minutes, input.seconds);

    var interval = intervalTime;

    setInterval(function () {
        timestamp = new Date(timestamp.getTime() + interval * 1000);
        document.querySelector('.countdown2').innerHTML = timestamp.getHours() + 'h:' 
        + timestamp.getMinutes() + 'm:' + timestamp.getSeconds() + 's';
    }, Math.abs(interval) * 1000);

}
gameTimer(1);

```

reset function

```
 function resetFunc(){

   clearInterval(gameTimer(0))

}
let reset = document.getElementById('restart');
reset.addEventListener('click', resetFunc);

```

after this function i call the timer function again to restart the timer again but it's not working

```
gameTimer(1);

```
