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 );

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。

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));

你也可以尝试将日期时区转换为印度:

var indianTimeZoneVal = new Date().toLocaleString('en-US', {timeZone: 'Asia/Kolkata'});
var indainDateObj = new Date(indianTimeZoneVal);
indainDateObj.setHours(indainDateObj.getHours() + 5);
indainDateObj.setMinutes(indainDateObj.getMinutes() + 30);
console.log(indainDateObj);

This is UTC date; converting UTC to IST timezone; let sampleArray = [ { date: "2022-12-22T19:16:26.803" }, { date: "2022-12-22T19:16:26.77" }, { date: "2022-12-22T19:16:26.737" }, { date: "2022-12-22T19:16:26.72" } ]; // Get all the results whose boolresult is 'true' // solution 1 sampleArray.map((element) => { let utcDate = new Date(element.date).getTime(); let dateIST = new Date(utcDate); dateIST.setHours(dateIST.getHours() + 5); dateIST.setMinutes(dateIST.getMinutes() + 30); element.date = dateIST; }); console.log("Result ==>>", sampleArray); // solution 2 sampleArray.map((element) => { element.date = new Date(element.date).toLocaleString("en-US", { timeZone: "Asia/Kolkata" }); }); console.log("Result 2==>>", sampleArray);

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`
);
