var timer; function countdowntime if time 0 time--; var minutes = Mathfloortime 60; var seconds = time 60; $clocktextminutes + + seconds 10 0 + seconds; else

There are a few issues with your code.

First, when you call setInterval, you need to pass a function reference as the first argument, not the result of a function call. In your code, you are immediately calling the countdown function and passing its result to setInterval. Instead, you should pass just the function name without the parentheses, like this:

timer = setInterval(countdown, 1000, 70);

Second, when you click on the .clock element, you are calling setInterval again without clearing the previous interval. This means that multiple intervals will be running simultaneously, causing unexpected behavior. To fix this, you should clear the previous interval before starting a new one.

Here's the updated code:

var timer;

function countdown(time) {
  if (time > 0) {
    time--;
    var minutes = Math.floor(time / 60);
    var seconds = time % 60;
    $('.clock').text(minutes + ':' + (seconds < 10 ? '0' : '') + seconds);
  } else {
    clearInterval(timer);
    // trigger event here
  }
}

timer = setInterval(countdown, 1000, 70);

$(document).on('click', '.clock', function() {
  clearInterval(timer);
  timer = setInterval(countdown, 1000, 20);
});

This code should fix the issues and make your timer work correctly
