如何使这个javascript函数实际收集服务器时间和倒计时，直到事件开始而不是浏览器/客户端时间

正如标题所说，我对此并不擅长，我正在努力如何在启动事件计时器时倒计时，直到事件开始从服务器获取时间并且不指望浏览器/客户端时间？以目前的方式，所有人都会错过该事件，因为大多数事件都有不同的时区及其不正确的:)

请给我一个线索。这是完整的功能：

<?php $d = date('D M d Y H:i:s O'); ?>
<script type="text/javascript">
var currdate = new Date(<?php $d; ?>);
var day = currdate.getDay();
var hrs = currdate.getHours();
var hrs0 = currdate.getHours();
var hrs00 = currdate.getHours();
var mins = currdate.getMinutes();
var secs = currdate.getSeconds();
