Have you inspected the headers?

Well, I tried, but I could not find anything useful (or may be I am not looking for the correct info):

Accept-Encoding: gzip[CRLF]
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5[CRLF]
Accept-Language: it-it,it;q=0.8,en-us;q=0.5,en;q=0.3[CRLF]
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7[CRLF]
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en; rv:1.8.0.10) Gecko/20070216 Firefox/1.5.0.10 Web-Sniffer/1.0.24[CRLF]

Is there any way to have the info from the request.getLocale()? I didn't think so but may be I'm worng...

cheers

The method request.getLocale() will give you a Locale object.

Using this object, you can call getter methods to get the language, country etc. But this will not give you a timezone (At least from my knowledge).

A workaround would be to use JavaScript.

In your JSP, have a hidden form variable which will be set to the the timezone from the client system.

A sample javascript code that would get you the timezone offset is shown below:

<script language="JavaScript1.3">
<!-- 
var userDate = new Date();
var userTimeZone = ( userDate.getTimezoneOffset()/60 )*( -1 );

alert("Timezone = " + userTimeZone );
// --> 
</script> 

The hidden form value can be retrieved from your request object and you can do the necessary processing.
