Getting the date/time from the client
Hi All,
I am doing a project in jsp/servlet and tomcat, which requires to take
the client date/time (ie the time of the machine the browser is
running). Is there any way to accomplish this ?
Thanks & regards
Vinu

I was playing devil's advocate -- since we don't really know the OP's

A good devil's advocate question, or was it rhetorical?
Either way it's got exactly the answer you'd expect, you'll set the date
to whatever Locale the Request returns. Obviously.

Is that really appropriate?? What if I have my Locale set to France, and my

Re: Getting the date/time from the client
Posted by Pid <p...@pidster.com>.
write a filter that activates for that url, and get the time just before
you doFilter. if you need to, you can pass the date obj as an attribute
Date date = new Date();
hreq.setAttribute("thisIsTheDate", date);
chain.doFilter(hreq, hres);

Re: Getting the date/time from the client
Posted by Jon Wingfield <jo...@mkodo.com>.
The HTTP spec (rfc2616) says clients should only send the Date header
with http messages with body content (POST, PUT) and even then it's
optional.
Try adding a date string as a parameter on your GET request which your
servlet can then parse from request.getParameter(...).
One way to do this would be to change your link to a form with a hidden
input field for your date value. Add an onclick/onsubmit javascript
handler to your form button which sets the value of the hidden field to
the current date in a format that your servlet will understand.
for example:
function setDate(form) {
form.dateField.value = new Date().toString();
}
Example assumes a hidden form input field with name dateField.

Re: Getting the date/time from the client
Posted by Shinya Koizumi <sk...@basicengineering.ca>.
uh...
no luck yet. getDateHeader only returns the date value when
you have some query strings in date format.
So, send the time as a part of query string like this
index.jsp?requesttime="25:40:12" or something similar.
If one has a better solution let him know.

Re: Getting the date/time from the client
Posted by Vinu Varghese <vi...@x-minds.org>.
SK,
That javascript prints the current client time. But I want the client
time with the request.
The scenario is :
I have a index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
Client time : <a href="clienttime.htm"> Click</a>
</body>
</html>
and a servlet that can take the client time (Hoping to :-) ) which is
mapped to 'clienttime.htm'
protected void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType("text/plain");
long time = request.getDateHeader("Date"); // Hoping to get the
client date.
PrintWriter out = response.getWriter();
out.println("Server time " + new Date());
out.println("Client time (long) " + time);
out.println("Client time " + new Date(time));
}
Is there any way to do this (get the client time from the request) ?
Or Am I trying to do a dumb thing ? ;)
Thanks & Regards

Yeah, you are right about it, I can't get getDateHeader working.
For the solution one, I have setup like this for jsp and worked.
<%@ page session="false" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title><%= application.getServerInfo() %></title>

Current Time:

out.println("var currentTime = new Date();");
out.println("document.write(currentTime.toLocaleString());");
out.println("</SCRIPT>");
out.println("</HEAD>");

Re: Getting the date/time from the client

Thanks SK,
I tried the second solution , but request.getDateHeader("Date") returns -1 .
Also I didn't understand the first solution ( embed a javascript), Can u
pls elaborate that.
Thanks and regards

Re: Getting the date/time from the client

One is to embed javascript in the output
out.println("<HTML><HEAD><title>JavaScriptExample</title>");
out.println("<SCRIPT LANGUAGE=JavaScript>");
out.println("function back() {");
out.println("history.back(-1);");
out.println("}");
out.println("</SCRIPT>");
out.println("</HEAD>");
The other solution is to get it from the request header.
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
long l = request.getDateHeader("Date");
Date d = new Date(l);
System.out.println(d);
}

Hi,
May be you can use:
request.getDateHeader()
Have a look at, there is a related thread there:
