JSP page display wrong time when compared to the server time

Question

Hi,
This problem seems to weird but it is happening
I have web application running where time is displayed in the page. In this application time is very critical. Currently, time is an hour behind the orginal time.
I checked the server it is displaying proper time.
As a matter of troubleshooting, I wrote a java program and run the program in the same server, where the application is running. The java program returns me proper time , but JSP is still displaying time an hour behind. To trouble shoot further, I created a test jsp page to just display the time and accessed the time and the jsp displayed wrong time as well, an hour behind.
I am running[ tomcat 4.0.3 and j2sdk1.4.3 in suse linux enterprise server 9.0
My Java program
import java.util.*;
import java.text.*;
public class TestDate
public static void main(String s[])
     try{
          DateFormat DF = new SimpleDateFormat( "dd/MM/yyyy");
DateFormat DT = new SimpleDateFormat("hh:mm aa");
          SimpleDateFormat fmt=new SimpleDateFormat("HH.mm");
          Calendar cal= Calendar.getInstance();
          java.util.Date dt=cal.getTime();
          String curdt=DT.format(dt);
          System.out.println("Server Time" + curdt + "\n");
          int hh = cal.get(Calendar.HOUR);
          int mm = cal.get(Calendar.MINUTE);
          int aa = cal.get(Calendar.AM_PM);
          System.out.println("Time" + hh +":"+mm+":"+aa+"\n");
     }catch(Exception e) {
     e.printStackTrace();
This display Time3:30:1
My JSP Page
<%@ page import="java.util.*,java.text.*"%>
<%
Calendar calen;
calen = Calendar.getInstance();
int hh=calen.get(Calendar.HOUR);
     int mm=calen.get(Calendar.MINUTE);
     int aa=calen.get(Calendar.AM_PM);
%>
<%=hh%> <%=mm%> <%=aa%>
This display 2 30 1
When I run Date in linux server it gives 3:30 PM EST 2004
I am really confused, why this is happening, If you have any solutions or idea please post the solution.

Answer 1

My guess is that the weirdness is caused by Daylight savings time.
I will presume that you and the server are in the same timezone :-)
Alternatively it could be caused by getting a different Locale.
Try the following
Print out "date.getTime()" value (ie long representing number of millis)
They should be the same (or close) in both the app and in JSP
Try simple date format in your JSP as well - what does that result in?
Print the calendar object, and look for the difference.
It might be in Locale, Timezone, or whether DST is set or not.
Hope this helps,
