I'm writing a counting script who counts the time between an old date and today.

Everything worked good until I tested on a computer with wrong date and saw the results.

So I found a way to get NTP time via http://json-time.appspot.com/time.json.

The problem is that I need the current time every millisecond because I want to count the milliseconds but Its impossible the send request to the NTP server every milisecond.

This is some example code to see what I'm writing about

            var today;

        $(document).ready(function(){



            $.data = function(success){

                $.get(http://json-time.appspot.com/time.json?callback=?, function(response){

                    success(new Date(response.datetime));

                }, json);

            };

        });



        function update(){

            var start = new Date(March 25, 2011 17:00:00);

            //var today = new Date();

            $.data(function(time){

                today = time;

            });

            var bla = today.getTime() - start.getTime();

            $(#milliseconds).text(bla);

        }



        setInterval(update(), 1);
