Convert Jquery date to custom timezone by timezone id
===

I have to display datetime value on my real time page and i have done following jquery function for that.

     function DisplayTimer() {
                var x = new Date();
                $('#<%=lblTimer.ClientID %>').html(x.toString());
                setTimeout('DisplayTimer()', 5000);
            }

now i have **timezonid** value in my **session object** how can i convert above date value to custom timezone using timezonid session value and also want set **datetime format** as per **culture of user's browser** through this jquery function. I have solution in server side code so using [webmethod] i can do that it will make separate request for that every 5 second so i would like to do that without server side interaction. please help me if anyone done this type of logic.

Thanks in adavance.
