JSTL format timestamp, for example, how can 1444226313 be displayed as 2015/10/7 21:58:33? Look at the following code:
<jsp:useBean id="myDate" class="java.util.Date"/>
<c:set target="${myDate}" property="time" value="${data.timestamp*1000}"/>
<fmt:formatDate pattern="yyyy-MM-dd hh:mm:ss" value="${myDate}" type="both"/> parameter myDate is customize,
parameter data.timestamp is pushed by server.
