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

<script type="text/javascript">

      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() { }

[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"); 
}

回调之前返回火灾;你必须使用回调来设置一些值。在成功或失败的回调中，您需要将日期传递给HTML元素或分配全局变量。
