大多数浏览器都支持带参数的toLocaleString函数，旧的浏览器通常会忽略这些参数。

const str = new Date()。toLocaleString('en-US'， {timeZone: '亚洲/雅加达'}); console.log (str);

服务器有问题，选择gmt+0000标准时区，你可以在javascript中使用moment-timezone库来更改它

const moment = require("moment-timezone")
const dateNew = new Date()
const changeZone = moment(dateNew);
changeZone.tz("Asia/Karachi").format("ha z");
// here you can paste "your time zone string"

我应该指出，我在可以使用的外部库方面受到了限制。moment.js和timezone-js不是我的选择。

我拥有的js日期对象是UTC。我需要在特定的时区(在我的例子中是“America/Chicago”)从这个日期获得日期和时间。

 var currentUtcTime = new Date(); // This is in UTC

 // Converts the UTC time to a locale specific format, including adjusting for timezone.
 var currentDateTimeCentralTimeZone = new Date(currentUtcTime.toLocaleString('en-US', { timeZone: 'America/Chicago' }));

 console.log('currentUtcTime: ' + currentUtcTime.toLocaleDateString());
 console.log('currentUtcTime Hour: ' + currentUtcTime.getHours());
 console.log('currentUtcTime Minute: ' + currentUtcTime.getMinutes());
 console.log('currentDateTimeCentralTimeZone: ' +        currentDateTimeCentralTimeZone.toLocaleDateString());
 console.log('currentDateTimeCentralTimeZone Hour: ' + currentDateTimeCentralTimeZone.getHours());
 console.log('currentDateTimeCentralTimeZone Minute: ' + currentDateTimeCentralTimeZone.getMinutes());

国际标准时间目前比“美国/芝加哥”早6小时。输出是:

currentUtcTime: 11/25/2016
currentUtcTime Hour: 16
currentUtcTime Minute: 15

currentDateTimeCentralTimeZone: 11/25/2016
currentDateTimeCentralTimeZone Hour: 10
currentDateTimeCentralTimeZone Minute: 15

提供所需的时区，例如“Asia/德黑兰”，以将当前时间更改为该时区。我用了“亚洲/首尔”。

您可以使用以下代码。如果需要更改样式。

请记住，如果你想要h:m:s格式而不是HH:MM:SS，你必须删除“函数kcwcheckT(i)”。

function kcwcheckT(i) { if (i < 10) { i = "0" + i; } return i; } function kcwt() { var d = new Date().toLocaleString("en-US", {timeZone: "Asia/Seoul"}); d = new Date(d); var h = d.getHours(); var m = d.getMinutes(); var s = d.getSeconds(); h = kcwcheckT(h); m = kcwcheckT(m); s = kcwcheckT(s); document.getElementById("kcwcurtime").innerHTML = h + ":" + m + ":" + s; var days = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]; document.getElementById("kcwcurday").innerHTML = days[d.getDay()] } kcwt(); window.setInterval(kcwt, 1000); @import url('https://fonts.googleapis.com/css2?family=Nunito&display=swap'); .kcwsource {color:#040505;cursor: pointer;display:block;width: 100%;border: none;border-radius:5px;text-align:center;padding: 5px 10px 5px 10px;} .kcwsource p {font-family: 'Nunito', sans-serif;} .CurTbx {color:#040505;cursor: pointer;display:block;width: 100%;border: none;border-radius:5px;text-align:center;padding: 5px 10px 5px 10px;} .kcwcstyle {font-family: 'Nunito', sans-serif; font-size: 22px;display: inline-block;} .kcwcurstinf {font-family: 'Nunito', sans-serif; font-size: 18px;display: inline-block;margin: 0;} .kcwcurday {margin: 0;} .kcwcurst {margin: 0 10px 0 5px;} /*Using the css below you can make your style responsive!*/ @media (max-width: 600px){ .kcwcstyle {font-size: 14px;} .kcwcurstinf {font-size: 12px;} } <div class="kcwsource"><p>This Pen was originally developed for <a href="http://kocowafa.com" target="_blank">KOCOWAFA.com</a></p></div> <div class="CurTbx"><p class="kcwcurst kcwcstyle" id="kcwcurday"></p><p class="kcwcurst kcwcstyle" id="kcwcurtime"></p><p class="kcwcurstinf">(Seoul, Korea)</p></div>

时区当前时区的偏移量

date +%s -d '1 Jan 1970'

对于我所在的GMT+10时区(澳大利亚)，它返回-36000

如果你只需要转换时区，我已经上传了一个精简版的moment-timezone，只有最基本的功能。其~1KB +数据:

S.loadData({
    "zones": [
        "Europe/Paris|CET CEST|-10 -20|01010101010101010101010|1GNB0 1qM0 11A0 1o00 11A0 1o00 11A0 1o00 11A0 1qM0 WM0 1qM0 WM0 1qM0 11A0 1o00 11A0 1o00 11A0 1qM0 WM0 1qM0|11e6",
        "Australia/Sydney|AEDT AEST|-b0 -a0|01010101010101010101010|1GQg0 1fA0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1fA0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0 1cM0|40e5",
    ],
    "links": [

});

let d = new Date();
console.log(S.tz(d, "Europe/Madrid").toLocaleString());
console.log(S.tz(d, "Australia/Sydney").toLocaleString());
