Convert date to another timezone in JavaScript

Question

I am looking for a function to convert date in one timezone to another.

It need two parameters,

• date (in format \"2012/04/10 10:10:30 +0000\")

Answer 1

Provide the desired time zone, for example "Asia/Tehran" to change the current time to that timezone. I used "Asia/Seoul".

You can use the following codes. change the style if you need to do so.

please keep in mind that if you want to have h:m:s format instead of HH:MM:SS, you'll have to remove "function kcwcheckT(i)".

function kcwcheckT(i) {
  if (i < 10) {
    i = "0" + i;
  }
  return i;
}
function kcwt() {
var d = new Date().toLocaleString("en-US", {timeZone: "Asia/Seoul"});
d = new Date(d);
  var h = d.getHours();
  var m = d.getMinutes();
  var s = d.getSeconds();
  h = kcwcheckT(h);
  m = kcwcheckT(m);
  s = kcwcheckT(s);
  document.getElementById("kcwcurtime").innerHTML = h + ":" + m + ":" + s;
  var days = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
document.getElementById("kcwcurday").innerHTML = days[d.getDay()]
}
kcwt();
window.setInterval(kcwt, 1000);

@import url('https://fonts.googleapis.com/css2?family=Nunito&display=swap');

.kcwsource {color:#040505;cursor: pointer;display:block;width: 100%;border: none;border-radius:5px;text-align:center;padding: 5px 10px 5px 10px;}
.kcwsource p {font-family: 'Nunito', sans-serif;}


.CurTbx {color:#040505;cursor: pointer;display:block;width: 100%;border: none;border-radius:5px;text-align:center;padding: 5px 10px 5px 10px;}
.kcwcstyle {font-family: 'Nunito', sans-serif; font-size: 22px;display: inline-block;}
.kcwcurstinf {font-family: 'Nunito', sans-serif; font-size: 18px;display: inline-block;margin: 0;}
.kcwcurday {margin: 0;}
.kcwcurst {margin: 0 10px 0 5px;}

/*Using the css below you can make your style responsive!*/

@media (max-width: 600px){
  .kcwcstyle {font-size: 14px;}
  .kcwcurstinf {font-size: 12px;}
}
