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;
}

这对我来说很管用:

function convertUTCDateToLocalDate(date) {
    var newDate = new Date(date.getTime() - date.getTimezoneOffset()*60*1000);
    return newDate;   
}

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)"

我相信这是最好的解决方案:

  let date = new Date(objDate);
  date.setMinutes(date.getTimezoneOffset());

这将根据偏移量适当地更新您的日期，因为它是以分钟为单位的。

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;
}
