如何制作一个倒计时的程序？
见下：
<%
CountdownDate = #1/1/2008 00:00:00AM#
If Date >= CountdownDate Then
Response.Write \"2008 北京\"
Response.End
End If
theDate = Now
DaysLeft = DateDiff(\"d\
theDate = DateAdd(\"d\
HoursLeft = DateDiff(\"h\
theDate = DateAdd(\"h\
MinutesLeft = DateDiff(\"n\
theDate = DateAdd(\"n\
SecondsLeft = DateDiff(\"s\
%>
现在时间: <%= Now %>
距离2008年还有 <%= DaysLeft%>天<%= HoursLeft %> 小时<%= MinutesLeft %>分 <%= SecondsLeft %>秒
