以下是基于Adorjan Princ的回答的简化解决方案:

function convertUTCDateToLocalDate(date) {
    var newDate = new Date(date);
    newDate.setMinutes(date.getMinutes() - date.getTimezoneOffset());
    return newDate;
}

或者更简单(尽管它会改变原始日期):

function convertUTCDateToLocalDate(date) {
    date.setMinutes(date.getMinutes() - date.getTimezoneOffset());
    return date;
}

用法:

var date = convertUTCDateToLocalDate(new Date(date_string_you_received));

对于TypeScript用户，这里有一个helper函数:

// Typescript Type: Date Options
interface DateOptions {
  day: 'numeric' | 'short' | 'long',
  month: 'numeric',
  year: 'numeric',
  timeZone: 'UTC',
};

// Helper Function: Convert UTC Date To Local Date
export const convertUTCDateToLocalDate = (date: Date) => {
  // Date Options
  const dateOptions: DateOptions = {
    day: 'numeric',
    month: 'numeric',
    year: 'numeric',
    timeZone: 'UTC',
  };

  // Formatted Date (4/20/2020)
  const formattedDate = new Date(date.getTime() - date.getTimezoneOffset() * 60 * 1000).toLocaleString('en-US', dateOptions);
  return formattedDate;
};

将此用于UTC和本地时间转换，反之亦然。

//Covert datetime by GMT offset 
//If toUTC is true then return UTC time other wise return local time
function convertLocalDateToUTCDate(date, toUTC) {
    date = new Date(date);
    //Local time converted to UTC
    console.log("Time: " + date);
    var localOffset = date.getTimezoneOffset() * 60000;
    var localTime = date.getTime();
    if (toUTC) {
        date = localTime + localOffset;
    } else {
        date = localTime - localOffset;
    }
    date = new Date(date);
    console.log("Converted time: " + date);
    return date;
}

我创建了一个函数，将所有时区转换为本地时间。

我没有使用getTimezoneOffset()，因为它没有返回适当的偏移值

要求:

1. npm i moment-timezone

function utcToLocal(utcdateTime, tz) {
    var zone = moment.tz(tz).format("Z") // Actual zone value e:g +5:30
    var zoneValue = zone.replace(/[^0-9: ]/g, "") // Zone value without + - chars
    var operator = zone && zone.split("") && zone.split("")[0] === "-" ? "-" : "+" // operator for addition subtraction
    var localDateTime
    var hours = zoneValue.split(":")[0]
    var minutes = zoneValue.split(":")[1]
    if (operator === "-") {
        localDateTime = moment(utcdateTime).subtract(hours, "hours").subtract(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
    } else if (operator) {
        localDateTime = moment(utcdateTime).add(hours, "hours").add(minutes, "minutes").format("YYYY-MM-DD HH:mm:ss")
    } else {
        localDateTime = "Invalid Timezone Operator"
    }
    return localDateTime
}

utcToLocal("2019-11-14 07:15:37", "Asia/Kolkata")

//Returns "2019-11-14 12:45:37"

JSON日期字符串(在c#中序列化)看起来像“2015-10-13T18:58:17”。

在angular中，(遵循Hulvej)创建一个localdate过滤器:

myFilters.filter('localdate', function () {
    return function(input) {
        var date = new Date(input + '.000Z');
        return date;
    };
})

然后，像这样显示本地时间:

{{order.createDate | localdate | date : 'MMM d, y h:mm a' }}

我有一个类似的问题，我使用以下代码代码(JavaScript)转换UTC到本地时间

let a = new Date() .toString a = a.getFullYear () () + "-" + ( a.getMonth () + 1) .toString()。padStart(2， "0") + "-" + a.getDate(). tostring()。padStart(“0”) console.log (a)
