<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
<title>My JSP 'time4.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
-->
</head>
<body>
<%
java.text.SimpleDateFormat simpleDateFormat = new java.text.SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
java.util.Date currentTime = new java.util.Date();
String time = simpleDateFormat.format(currentTime).toString();
out.println("当前时间为:"+time);
%>
