Thanks for your explanation, let me check if the meta:refresh tag can be supported in most of browsers

He's suggesting you use the javascript or method or META:REFRESH tag.

if you put a meta:refresh tag in the <head> of the document, the browser
will re-direct to a specified url after a specified number of seconds
(e.g.
content=300 means it will re-direct after 300 seconds).

   <head>
        <meta http-equiv="refresh" content="300;
url='/myWebApp/myAction.do'" />
   </head>

What you would need to do is calculate out how many seconds it is until
9:00pm when you generate the page in order to specify the right amount of
time in the "content". One way to do this would be to write your own
custom
tag and make the time configurable for your web app.

What I don't know is what browsers support the meta:refresh tag.
