服务器时间而不是客户端时间JAVASCRIPT

Question

Is it possible to use this script with server time instead of client time. (For checking if time is past) It now uses client time and thats a problem. (Maybe with php??)

<script>
var end = new Date('02/19/2012 10:1 AM');

    var _second = 1000;
    var _minute = _second * 60;
    var _hour = _minute * 60;
    var _day = _hour * 24;
    var timer;

    function showRemaining() {
        var now = new Date();
        var distance = end - now;
        if (distance < 0) {

            clearInterval(timer);
            document.getElementById('countdown').innerHTML = 'EXPIRED!';

            return;
        }
        var days = Math.floor(distance / _day);
        var hours = Math.floor((distance % _day) / _hour);
        var minutes = Math.floor((distance % _hour) / _minute);
        var seconds = Math.floor((distance % _minute) / _second);

        document.getElementById('countdown').innerHTML = days + 'days ';
        document.getElementById('countdown').innerHTML += hours + 'hrs ';
        document.getElementById('countdown').innerHTML += minutes + 'mins ';
        document.getElementById('countdown').innerHTML += seconds + 'secs';
    }

    timer = setInterval(showRemaining, 1000);
</script>
<div id="countdown"></div>

Answer 1

You can get time from ajax request, or use something like this:

<?php
 $now = date('d-m-Y');
 $end= "01-01-2013"
 $date = strtotime($end) - strtotime($now);
 $days = date('d', $date);
 $monthes= date('m', $date);
 $years= date('Y', $date);
?> 
<script>
  var days = "<?= $days ?>";
  var monthes= "<?= $monthes?>";
  var years= "<?= $years?>";

    document.getElementById('countdown').innerHTML = days+ ' days';

    document.getElementById('countdown').innerHTML += monthes+ ' monthes';

    document.getElementById('countdown').innerHTML += years+ ' years';
</script>
