I think it will be better if you will create clock object. See code (see Demo: http://jsfiddle.net/f9X6J/):

var Clock = {
  totalSeconds: 0,

  start: function () {
    var self = this;

    this.interval = setInterval(function () {
      self.totalSeconds += 1;

      $("#hour").text(Math.floor(self.totalSeconds / 3600));
      $("#min").text(Math.floor(self.totalSeconds / 60 % 60));
      $("#sec").text(parseInt(self.totalSeconds % 60));
    }, 1000);
  },

  pause: function () {
    clearInterval(this.interval);
    delete this.interval;
  },

  resume: function () {
    if (!this.interval) this.start();
  }
};

Clock.start();

$('#pauseButton').click(function () { Clock.pause(); });
$('#resumeButton').click(function () { Clock.resume(); });
