如果你有一个时区偏移，你可以使用这个:

const timezoneDate = (timestamp: number, offsetInHours: number) => {
  const shiftedTimestam = timestamp + offsetInHours * 3600000;

  const shiftedDate = new Date(shiftedTimestam);

  return {
    date: shiftedDate.getUTCDate(),
    hours: shiftedDate.getUTCHours(),
    minutes: shiftedDate.getUTCMinutes(),
    // ...other UTC methods
  }
};

// Usage:
const newYorkDate = timezoneDate(Date.now(), -5);

console.log(
  `It is ${newYorkDate.hours}:${newYorkDate.minutes} in NYC`
);

大多数浏览器都支持带参数的toLocaleString函数，旧的浏览器通常会忽略这些参数。

const str = new Date()。toLocaleString('en-US'， {timeZone: '亚洲/雅加达'}); console.log (str);

我最近在Typescript中做了这个:

// fromTimezone example : Europe/Paris, toTimezone example: Europe/London
private calcTime( fromTimezone: string, toTimezone: string, dateFromTimezone: Date ): Date {
  const dateToGetOffset = new Date( 2018, 5, 1, 12 );

  const fromTimeString = dateToGetOffset.toLocaleTimeString( "en-UK", { timeZone: fromTimezone, hour12: false } );
  const toTimeString = dateToGetOffset.toLocaleTimeString( "en-UK", { timeZone: toTimezone, hour12: false } );

  const fromTimeHours: number = parseInt( fromTimeString.substr( 0, 2 ), 10 );
  const toTimeHours: number = parseInt( toTimeString.substr( 0, 2 ), 10 );

  const offset: number = fromTimeHours - toTimeHours;

  // convert to msec
  // add local time zone offset
  // get UTC time in msec
  const dateFromTimezoneUTC = Date.UTC( dateFromTimezone.getUTCFullYear(),
    dateFromTimezone.getUTCMonth(),
    dateFromTimezone.getUTCDate(),
    dateFromTimezone.getUTCHours(),
    dateFromTimezone.getUTCMinutes(),
    dateFromTimezone.getUTCSeconds(),
  );

  // create new Date object for different city
  // using supplied offset
  const dateUTC = new Date( dateFromTimezoneUTC + ( 3600000 * offset ) );

  // return time as a string
  return dateUTC;
}

我使用“en-UK”格式，因为它是一个简单的。可能是"en-US"之类的。

如果第一个参数是本地时区，第二个参数是目标时区，它将返回一个具有正确偏移量的Date对象。

对于moment.js用户，现在可以使用moment-timezone。使用它，你的函数看起来像这样:

function toTimeZone(time, zone) {
    var format = 'YYYY/MM/DD HH:mm:ss ZZ';
    return moment(time, format).tz(zone).format(format);
}

这对每个人都适用。您可以通过手动更改机器上的时间来测试不同的时区。这个函数将相应地进行调整。

 function getCurrentTime() {
     const d = new Date() //2022-07-22T16:27:21.322Z
     const t = d.getTime(); //d in milliseconds 1658507241322
     const offset = -d.getTimezoneOffset()/60 //current offset in hours -4
     const curretMilli = t + (offset * 3600000) //cuuret local time milliseconds need to convert offset to milliseconds
     return new Date(curretMilli) //converts current local time in milliseconds to a Date //2022-07-22T12:27:21.322Z
 }

我应该指出，我在可以使用的外部库方面受到了限制。moment.js和timezone-js不是我的选择。

我拥有的js日期对象是UTC。我需要在特定的时区(在我的例子中是“America/Chicago”)从这个日期获得日期和时间。

 var currentUtcTime = new Date(); // This is in UTC

 // Converts the UTC time to a locale specific format, including adjusting for timezone.
 var currentDateTimeCentralTimeZone = new Date(currentUtcTime.toLocaleString('en-US', { timeZone: 'America/Chicago' }));

 console.log('currentUtcTime: ' + currentUtcTime.toLocaleDateString());
 console.log('currentUtcTime Hour: ' + currentUtcTime.getHours());
 console.log('currentUtcTime Minute: ' + currentUtcTime.getMinutes());
 console.log('currentDateTimeCentralTimeZone: ' +        currentDateTimeCentralTimeZone.toLocaleDateString());
 console.log('currentDateTimeCentralTimeZone Hour: ' + currentDateTimeCentralTimeZone.getHours());
 console.log('currentDateTimeCentralTimeZone Minute: ' + currentDateTimeCentralTimeZone.getMinutes());

国际标准时间目前比“美国/芝加哥”早6小时。输出是:

currentUtcTime: 11/25/2016
currentUtcTime Hour: 16
currentUtcTime Minute: 15

currentDateTimeCentralTimeZone: 11/25/2016
currentDateTimeCentralTimeZone Hour: 10
currentDateTimeCentralTimeZone Minute: 15
