需要从指定丹麦时间到当前时间的倒计时计时器

Question

我需要一个倒计时计时器，使其显示在Prestashop包的产品页面。它应该计算丹麦的指定时间与本地系统的当前时间之间的差值。

例如：丹麦指定时间-16小时:00分钟:00秒丹麦时间系统当前时间- now()；

Specified_Time requiredTime =( var - current_Time)

我在这里添加了我的代码。我希望专家们能帮助我。

<p align="center"><span id="countdown"></span></p>
<script type="text/javascript">
// set the date we're counting down to
var target_date = new Date("Aug 15, 2019").getTime();

// variables for time units
var days, hours, minutes, seconds;

// get tag element
var countdown = document.getElementById("countdown");

// update the tag with id "countdown" every 1 second
setInterval(function () {

// find the amount of "seconds" between now and target
var current_date = new Date().getTime();
var seconds_left = (target_date - current_date) / 1000;

// do some time calculations
days = parseInt(seconds_left / 86400);
seconds_left = seconds_left % 86400;

hours = parseInt(seconds_left / 3600);
seconds_left = seconds_left % 3600;

minutes = parseInt(seconds_left / 60);
seconds = parseInt(seconds_left % 60);

// format countdown string + set tag value
countdown.innerHTML = days + "d, " + hours + "h, "
+ minutes + "m, " + seconds + "s";  

}, 1000);
</script>

请在这方面帮助我。

提前谢谢。

使用getTimezoneOffset()方法获取UTC和本地时间之间的差值，并找出UTC时间和丹麦时间之间的差值，这样您就可以在计算中包含此差值
