不带PHP的不同时区时钟？

Question

我正在尝试在我的页面上制作两个不同的时钟，一个只跟随DK时间作为标准，一个跟随用户的当地时间。然后我想，如果没有PHP，我可以这样做吗？到目前为止，我无法找到任何可以锁定DK手表时区的东西，而不会在用户计算机上的时间发生变化时更改它。 JS中是否有可以执行此操作的功能，还是需要PHP？

    clockS.css("transform", "rotate(" + s + "deg)");
  }

  var clock = setInterval(time, 1000);
  time();
  var clock = setInterval(timezone, 1000);
  timezone();
