    我来发一个最愚蠢的方法,抛砖引玉!

    function timeToStr(time) {
        var h = 0,
            m = 0,
            s = 0,
            _h = '00',
            _m = '00',
            _s = '00';
        h = Math.floor(time / 3600);
        time = Math.floor(time % 3600);
        m = Math.floor(time / 60);
        s = Math.floor(time % 60);
        _s = s < 10 ? '0' + s : s + '';
        _m = m < 10 ? '0' + m : m + '';
        _h = h < 10 ? '0' + h : h + '';
        return _h + ":" + _m + ":" + _s;
    }

    这个得自己写了。

    //将时间处理为 2015-2-2 11:45:31 的格式
    var formatLocalDate = function(now) {
      if(!now)
        now = new Date();
      else
        now = new Date(now);
      var tzo = -now.getTimezoneOffset(),
          dif = tzo >= 0 ? '+' : '-',
          pad = function(num) {
              norm = Math.abs(Math.floor(num));
              return (norm < 10 ? '0' : '') + norm;
          };
      return now.getFullYear()
        + '-' + pad(now.getMonth()+1)
        + '-' + pad(now.getDate())
        + ' ' + pad(now.getHours())
        + ':' + pad(now.getMinutes())
        + ':' + pad(now.getSeconds());
    };
