Answers for "javascript get timezone time"

javascript set date to timezone

var d = new Date("2020-04-13T00:00:00.000+08:00"); /* midnight in China on April 13th */
d.toLocaleString('en-US', { timeZone: 'America/New_York' });
//=> "4/12/2020, 12:00:00 PM"
// (midnight in China on April 13th is noon in New York on April 12th)

javascript get specific timezone

function changeTimezone(date, ianatz) {

  // suppose the date is 12:00 UTC
  var invdate = new Date(date.toLocaleString('en-US', {
    timeZone: ianatz
  }));

  // then invdate will be 07:00 in Toronto
  // and the diff is 5 hours
  var diff = date.getTime() - invdate.getTime();

  // so 12:00 in Toronto is 17:00 UTC
  return new Date(date.getTime() - diff); // needs to substract

}

// E.g.
var here = new Date();
var there = changeTimezone(here, "America/Toronto");

console.log(`Here: ${here.toString()}\nToronto: ${there.toString()}`);
