在JavaScript中，我使用:

var updaated_time= "2022-10-25T06:47:42.000Z"

{{updaated_time | date: 'dd-MM-yyyy HH:mm'}} //output: 26-10-2022 12:00

在javascript中将字符串转换为日期之前，将'UTC'附加到字符串中:

var date = new Date('6/29/2011 4:52:48 PM UTC');
date.toString() // "Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)"

在JavaScript中，我使用:

var updaated_time= "2022-10-25T06:47:42.000Z"

{{updaated_time | date: 'dd-MM-yyyy HH:mm'}} //output: 26-10-2022 12:00

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;
}

我写了一个漂亮的小脚本，它采用UTC纪元并将其转换为客户端系统时区，并以d/m/Y H: I:s(类似于PHP date函数)格式返回:

getTimezoneDate = function ( e ) {

    function p(s) { return (s < 10) ? '0' + s : s; }        

    var t = new Date(0);
    t.setUTCSeconds(e);

    var d = p(t.getDate()), 
        m = p(t.getMonth()+1), 
        Y = p(t.getFullYear()),
        H = p(t.getHours()), 
        i = p(t.getMinutes()), 
        s = p(t.getSeconds());

    d =  [d, m, Y].join('/') + ' ' + [H, i, s].join(':');

    return d;

};

Matt的回答忽略了一个事实，即Date()和它需要转换的日期时间之间的夏令时可能不同-这是我的解决方案:

    function ConvertUTCTimeToLocalTime(UTCDateString)
    {
        var convertdLocalTime = new Date(UTCDateString);

        var hourOffset = convertdLocalTime.getTimezoneOffset() / 60;

        convertdLocalTime.setHours( convertdLocalTime.getHours() + hourOffset ); 

        return convertdLocalTime;
    }

调试器中的结果:

UTCDateString: "2014-02-26T00:00:00"
convertdLocalTime: Wed Feb 26 2014 00:00:00 GMT-0800 (Pacific Standard Time)
