这是为我工作在React本机应用程序。

import moment from 'moment-timezone'

function convertTZ(date, tzString) {
  const formatedDate = moment(date).tz(tzString).format()
  return formatedDate
}

export {convertTZ}

无耻地窃取自:http://www.techrepublic.com/article/convert-the-local-time-to-another-time-zone-with-this-javascript/6016329

/** 
 * function to calculate local time
 * in a different city
 * given the city's UTC offset
 */
function calcTime(city, offset) {

    // create Date object for current location
    var d = new Date();
   
    // get UTC time in msec
    var utc = d.getTime();
   
    // create new Date object for different city
    // using supplied offset
    var nd = new Date(utc + (3600000*offset));
   
    // return time as a string
    return "The local time in " + city + " is " + nd.toLocaleString();
}

这个函数通过提供城市/国家的名称和偏移值来计算时区值

你可以使用Intl。DateTimeFormat指定时区作为选项，它将日期或时间转换为所需的时区。

let timezone = "Asia/Jakarta";
let date = new Date("2012/04/10 10:10:30 +0000");
let formattedDate = new Intl.DateTimeFormat("en-US", { dateStyle: "long" , timeStyle: "short",  timeZone: timezone}).format(date);

这是为我工作在React本机应用程序。

import moment from 'moment-timezone'

function convertTZ(date, tzString) {
  const formatedDate = moment(date).tz(tzString).format()
  return formatedDate
}

export {convertTZ}

所有这些答案都有点多余，但这对我来说是有效的，可以获得具有特定小时偏移量的当前Date对象。

function hourToMs(hour) { return hour * 60 * 1000 * 60; } function minToMs(min) { return min * 60 * 1000; } function getCurrentDateByOffset(offset) { // Get the current timezone in milliseconds to reset back to GMT aka +0 let timezoneOffset = minToMs((new Date()).getTimezoneOffset()); // get the desired offset in milliseconds, invert the value because javascript is dum let desiredOffset = hourToMs(offset * -1); return new Date(Date.now() + timezoneOffset - desiredOffset); } // -6 hours is central timezone console.log("The time is: " + getCurrentDateByOffset(-6));

设置一个变量，用-符号分隔年、月和日，加上一个T和HH:mm:ss模式的时间，在字符串末尾加上+01:00(在我的例子中，时区是+1)。然后使用此字符串作为日期构造函数的参数。

// desired format: 2001-02-04T08:16:32+01:00
dateAndTime = year+"-"+month+"-"+day+"T"+hour+":"+minutes+":00+01:00";

var date = new Date(dateAndTime );
