How to send system timezone to a servlet using javascript

Question

I want to send system timezone to servlet using javascript . How could I do it when I submit a button on JSP ? .

This is javascript code .

<script>
    function dateReturn() {
          var date = document.getElementById("demo").innerHTML = Date();
          return date;
    }
</script>

Read the timezone offset and send it as a separate field or combine date and offset together in 1 item and parse it on server side.

var d = new Date()
var n = d.getTimezoneOffset();

If I get whole description of timezone , how could I send it to a servlet ? – Terance Wijesuriya Oct 13 '15 at 08:08
In example I've added variable D contains time, date and N keeps Timezone/Offset. You have everything there. – Dmytro Pastovenskyi Oct 13 '15 at 08:10

try this for retrieve timezone. you can adjust the substring function for retrieve other details from date object.

var d = new Date();
var s = d.toString();
var timezone= s.substring(s.indexOf("(")+1, s.indexOf(")"));
