这么简单，我居然实现不了。

实现的功能如下：http://www.dynamicdrive.com/dynamicindex6/universalcountdown.htm
可是我怎么老是得到的是：
NaN days NaN hours NaN minutes NaN
谁能帮我看看。谢谢了。

“NaN”，你肯定在js中没有把字符串转成时间类型
各位朋友，代码如下：
var servertimestring=(servermode=="server-asp")? '<? print date("F d, Y H:i:s", time())?>' : (servermode=="server-ssi")? '' : '<%= Now() %>'
错误就是以下两行：
'
可是怎么改也得不到服务器时间呀
是不是不支持SSI呀。所以就把那两条语句，给注释掉了。只是怀疑。可是又怎么让他支持SSI呢。不明白。唉。郁闷。兄弟们，再帮我看看吧。
你把格式改成　这样　就行了June 10, 2007 21:52:06
上面的兄弟，改为June 10, 2007 21:52:06
可是这样改的话，时间，不动了。总是停留在那个时间上了。意思讲。时间不倒退了。你一刷新页面。时间，又变成刚开始的时间了。
June 10, 2007 21:52:06　我是在告诉你格式　不是让你它来用。。你在后台输出　这样的格式就行了。。我在找C#的函数。。你要是不想自己弄　就等等我做完。。
C#　的　读服务器时间<%@ Page Language="C#" AutoEventWireup="true" %>

这是我写的：
function Locationtime()
{
var d = new Date()
var vYear = d.getFullYear()
var vMon = d.getMonth() + 1
var vDay = d.getDate()switch(vMon)
{
  case 1:
    vMon="January";
break;
  case 2:
    vMon="February";
break;
  case 3:
    vMon="March";
break;
  case 4:
    vMon="April";
break;
  case 5:
    vMon="May";
break;
  case 6:
    vMon="June";
break;
  case 7:
    vMon="July";
break;}
document.write(vMon)document.write(" ")document.write(vDay<10 ?  "0"+ vDay : vDay )
document.write(", ")document.write(vYear)
document.write(" ")
var vHour = d.getHours()
var vMin = d.getMinutes()
var vSec = d.getSeconds()document.write(vHour<10 ? "0" + vHour : vHour)
document.write(":")
document.write(vMin<10 ? "0" + vMin : vMin)
document.write(":")
document.write(vSec<10 ?  "0"+ vSec : vSec )
}
然后改成：
var servertimestring=(servermode=="server-php")? '<? print date("F d, Y H:i:s", time())?>' : (servermode=="server-ssi") ? Locationtime() : '<%= Now() %>'还是不行。
//var servertimestring=(servermode=="server-php")? '<? print date("F d, Y H:i:s", time())?>' : (servermode=="Server-Aspx")? '<%=DateTime.Now.ToString("MMMM dd, yyyy HH:mm:ss", new CultureInfo("en-US")) %>' : '<%=DateTime.Now.ToString("MMMM dd, yyyy HH:mm:ss", new CultureInfo("en-US")) %>'
this.localtime=this.serverdate=new Date(<%=DateTime.Now.Year%>,<%=DateTime.Now.Month%>,<%=DateTime.Now.Day%>,<%=DateTime.Now.Hour%>,<%=DateTime.Now.Minute%>,<%=DateTime.Now.Second%>);
