我的javascript时钟不同步

Question

我从朋友那里得到了一些帮助，他写了一个信标计时器：My timer

如果我们将它与此Not my timer进行比较，它就会停止运行insync 那一个仍然是不相干的。我不知道我忘了添加到我的代码中。 两个网站都抓住了当地时间，所以即使我的电脑时钟不同步，这两个页面也应该是不同步的。

 var elements = [
    ["4U1UN", "New York"],
    ["VE8AT", "Canada"],
    ["W6WX", "California"],
    ["KH6WO", "Hawaii"],
    ["ZL6B", "New Zealand"],
    ["VK6RBP", "Australia"],
    ["JA2IGY", "Japan"],
    ["RR9O", "Novosibirsk"],
    ["VR2B", "Hong Kong"],
    ["4S7B", "Sri Lanka"],
    ["ZS6DN", "South Africa"],
    ["5Z4B", "Kenya"],
    ["4X6TU", "Israel"],
    ["OH2B", "Finland"],
    ["CS3B", "Madeira"],
    ["LU4AA", "Argentina"],
    ["OA4B", "Peru"],
    ["YV5B", "Venezuela"]
];
var initial = ["28200", "24930", "21150", "18110", "14100"];

var timing = 10; //seconds per element of array

window.setInterval(function () {
    var d = new Date();
    var second = (d.getMinutes() * 60) + d.getSeconds();

    var test = Math.floor(((second +1.1) % (elements.length * timing)) / timing);

    document.getElementById("wat").innerHTML = "";
    for(var i = 0; i < elements.length; i++)
    {
        var index = (i + test) % elements.length;
        document.getElementById("wat").innerHTML += "<tr><td>" + 
            ( i < initial.length ? initial[i] : "") + 
            "</td><td>" + 
            elements[index][0] + 
            "</td><td>" + 
            elements[index][1] + 
            "</td></tr>";
    }
}, 1000);
