Question

目标是使倒数计时器能够倒数到纽约市（EST）的特定时间。因此，计时器在纽约市的12:00变为零，但在洛杉矶，计时器将在09:00变为零

这是我在W3Schools中使用的代码。但是我没有足够的知识来添加时区。

任何人都可以帮助：)

<script>
// Set the date we're counting down to
var countDownDate = new Date("Dec, 2019 12:00:00 GMT-0500").getTime();

// Update the count down every 1 second
var x = setInterval(function() {

  // Get today's date and time
  var now = new Date().getTime();

  // Find the distance between now and the count down date
  var distance = countDownDate - now;

  // Time calculations for days, hours, minutes and seconds
  var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
  var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
  var seconds = Math.floor((distance % (1000 * 60)) / 1000);

  // Output the result in an element with id="demo"
  document.getElementById("demo").innerHTML = hours + "h "
  + minutes + "m " + seconds + "s ";

  // If the count down is over, write some text 
  if (distance < 0) {
    clearInterval(x);
    document.getElementById("demo").innerHTML = "EXPIRED";
  }
}, 1000);
</script>
