单纯采用js，new Date()，页面上实时显示的是客户端的时间。

<div id="showDateTime"><script type="text/javascript"
language="javascript">
setInterval("showDateTime.innerHTML='当前时间:'+new Date().toLocaleString();",1000);
</script></div>

必须使用java+js，代码如下：

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ page import="java.util.*"%>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@ taglib uri="http://myfaces.apache.org/extensions" prefix="x"%>
<%@ taglib uri="http://www.ccb.cn/xmdc" prefix="xmdc"%>
<%@ taglib prefix="ig"
uri="http://www.infragistics.com/faces/netadvantage"%>
<%
Calendar cld = Calendar.getInstance();
cld.setTime(new Date());
int nian = cld.get(Calendar.YEAR);
int yue = cld.get(Calendar.MONTH);
int ri = cld.get(Calendar.DATE);
int si = cld.get(Calendar.HOUR_OF_DAY);
int fen = cld.get(Calendar.MINUTE);
int miao = cld.get(Calendar.SECOND);
%>
<xmdc:panelGrid columns="2" width="100%" columnClasses="left,right"
styleClass="top_bg">
<xmdc:graphicImage url="/supres/images/logo/logo1.gif" height="51" />
<xmdc:panelGrid styleClass="state">
  <x:panelGroup>
   <xmdc:outputText value=" 机构:#{SessionBean.userInfo.orgName}"
    title="#{SessionBean.userInfo.orgId}" />
   <xmdc:outputText value=" | 用户: #{SessionBean.userInfo.name}" />
   <f:verbatim>
    <div id="showDateTime"><SCRIPT language=javascript>

</SCRIPT></div>
   </f:verbatim>
   <xmdc:outputLink value="/laa/Logout.jsf">
    <xmdc:outputText value="【退出系统】" />
   </xmdc:outputLink>
  </x:panelGroup>
</xmdc:panelGrid>
</xmdc:panelGrid>

<xmdc:panelGrid width="100%" border="0" cellspacing="0" cellpadding="0"
columns="2" styleClass="menu">
<xmdc:panelGrid columns="3" border="0" cellspacing="0" cellpadding="0"
style="float:left">
<ig:menu id="menu" binding="#{userMenu}"></ig:menu>
</xmdc:panelGrid>
</xmdc:panelGrid>

另一个可以在server上直接运行的jsp：

<%@   page contentType="text/html;   charset=GB2312"%>
<%@   page import="java.util.*,java.text.*"%>
<%@   page language="java"%>
<HTML>
<HEAD>
<%java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat(
     "H:m:s");
   String ServerTime = formatter.format(new Date());

   %>
<Script Language="JavaScript">
var   t   =   "<%=ServerTime%>";
var   tt   =   t.split(":");
var   hour   =   parseInt(tt[0]);
var   minute   =   parseInt(tt[1]);
var   second   =   parseInt(tt[2]);
function   writeTime(){
second   ++;
if(second>59){
      second   =   0;
      minute   ++;
      }

if(minute   >   59){
minute   =   0;
hour   ++;
}

if(hour   >   23){hour   =   0;}
var   s   =   (hour<10?"0":"")   +   hour   +   ":"   +   (minute<10?"0":"")   +   minute   +   ":"   +   (second<10?"0":"")   +   second;
document.all("spanTime").innerHTML   =   s;
}
t   =   setInterval("writeTime()",   1000);
          </script>
</HEAD>
<BODY topmargin="0" leftmargin="2" rightmargin="0" bottommargin="0">
现在时刻：
<b><SPAN id="spanTime"></SPAN></b>
</body>
</HTML>
