如何使用“jquery.countdown.js”插件使倒计时与jquery同步?

无法获取正确的ans,因为我从jquery变量“short”获得了正确的结果,但当我与函数“serversync”同步时,所有设置都将设置为0:0:0,我已检查两个日期是否相同。 参考现场 http://keith-wood.name/countdown.html

这是我的密码

[WebMethod]
public static String GetTime()
{
    DateTime dt = new DateTime(); 
    dt = Convert.ToDateTime("April 9, 2010 22:38:10");  
    return dt.ToString("dddd, dd MMMM yyyy HH:mm:ss");
}

HTML文件

<script type="text/javascript" src="Scripts/jquery-1.3.2.js"></script>

<script type="text/javascript">
    $(function() {
        var shortly = new Date('April 9, 2010 22:38:10');

        //for loop divid
        /// 
        $('#defaultCountdown').countdown({
            until: shortly, onExpiry: liftOff, onTick: watchCountdown, serverSync: serverTime
        });

    });

    function serverTime() {
        var time = null;
        $.ajax({
            type: "POST",
            //Page Name (in which the method should be called) and method name
            url: "Default.aspx/GetTime",

        return time;

    }
    function watchCountdown() { }
    function liftOff() { }
