这是一个普遍的解决方案:

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

    var offset = date.getTimezoneOffset() / 60;
    var hours = date.getHours();

    newDate.setHours(hours - offset);

    return newDate;   
}

用法:

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

根据客户端本地设置显示日期:

date.toLocaleString();

根据@digitalbath的答案，下面是一个小函数，用于获取UTC时间戳，并在给定的DOM元素中显示本地时间(最后一部分使用jQuery):

https://jsfiddle.net/moriz/6ktb4sv8/1/

<div id="eventTimestamp" class="timeStamp">
   </div>
   <script type="text/javascript">
   // Convert UTC timestamp to local time and display in specified DOM element
   function convertAndDisplayUTCtime(date,hour,minutes,elementID) {
    var eventDate = new Date(''+date+' '+hour+':'+minutes+':00 UTC');
    eventDate.toString();
    $('#'+elementID).html(eventDate);
   }
   convertAndDisplayUTCtime('06/03/2015',16,32,'eventTimestamp');
   </script>

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;
}

在尝试了这里发布的其他一些没有好的结果之后，这似乎对我有用:

convertUTCDateToLocalDate: function (date) {
    return new Date(Date.UTC(date.getFullYear(), date.getMonth(), date.getDate(),  date.getHours(), date.getMinutes(), date.getSeconds()));
}

这是相反的，从本地日期到UTC:

convertLocalDatetoUTCDate: function(date){
    return new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
}

@Adorojan的回答几乎是正确的。但是添加偏移量是不正确的，因为如果浏览器日期在GMT之前，偏移量值将为负，反之亦然。 下面是我的解决方案，对我来说是完美的:

// Input time in UTC var inputInUtc = "6/29/2011 4:52:48"; var dateInUtc = new Date(Date.parse(inputInUtc+" UTC")); //Print date in UTC time document.write("Date in UTC : " + dateInUtc.toISOString()+"<br>"); var dateInLocalTz = convertUtcToLocalTz(dateInUtc); //Print date in local time document.write("Date in Local : " + dateInLocalTz.toISOString()); function convertUtcToLocalTz(dateInUtc) { //Convert to local timezone return new Date(dateInUtc.getTime() - dateInUtc.getTimezoneOffset()*60*1000); }

tl;dr (new Date('6/29/2011 4:52:48 PM UTC')).toString()

源字符串必须指定时区或UTC。

一行程序:

(new Date('6/29/2011 4:52:48 PM UTC')).toString()

结果在我的一个web浏览器:

"Wed Jun 29 2011 09:52:48 GMT-0700 (Pacific Daylight Time)"

这种方法甚至适当地选择标准/日光时间。

(new Date('1/29/2011 4:52:48 PM UTC')).toString()

结果在我的浏览器:

"Sat Jan 29 2011 08:52:48 GMT-0800 (Pacific Standard Time)"
