我正在寻找一个函数转换日期在一个时区到另一个。
它需要两个参数，
日期(格式为“2012/04/10 10:10:30 +0000”) 时区字符串("Asia/Jakarta")
时区字符串在http://en.wikipedia.org/wiki/Zone.tab中描述
有什么简单的方法吗?

如果你有一个时区偏移，你可以使用这个:
const timezoneDate = (timestamp: number, offsetInHours: number) => {
const shiftedTimestam = timestamp + offsetInHours * 3600000;
const shiftedDate = new Date(shiftedTimestam);
return {
date: shiftedDate.getUTCDate(),
hours: shiftedDate.getUTCHours(),
minutes: shiftedDate.getUTCMinutes(),
// ...other UTC methods
}
};
// Usage:
const newYorkDate = timezoneDate(Date.now(), -5);
console.log(
`It is ${newYorkDate.hours}:${newYorkDate.minutes} in NYC`
);
其他回答
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>
你可以使用to toLocaleString()方法来设置时区。
new Date().toLocaleString('en-US', { timeZone: 'Indian/Christmas' })
对于印度，你可以使用“印度/圣诞节”，以下是不同的时区，
"Antarctica/Davis",
"Asia/Bangkok",
"Asia/Hovd",
"Asia/Jakarta",
"Asia/Phnom_Penh",
"Asia/Pontianak",
"Asia/Saigon",
"Asia/Vientiane",
"Etc/GMT-7",
"Indian/Christmas"
This is UTC date; converting UTC to IST timezone; let sampleArray = [ { date: "2022-12-22T19:16:26.803" }, { date: "2022-12-22T19:16:26.77" }, { date: "2022-12-22T19:16:26.737" }, { date: "2022-12-22T19:16:26.72" } ]; // Get all the results whose boolresult is 'true' // solution 1 sampleArray.map((element) => { let utcDate = new Date(element.date).getTime(); let dateIST = new Date(utcDate); dateIST.setHours(dateIST.getHours() + 5); dateIST.setMinutes(dateIST.getMinutes() + 30); element.date = dateIST; }); console.log("Result ==>>", sampleArray); // solution 2 sampleArray.map((element) => { element.date = new Date(element.date).toLocaleString("en-US", { timeZone: "Asia/Kolkata" }); }); console.log("Result 2==>>", sampleArray);
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);
好了，找到了!
我使用的是timezone-js。这是代码:
var dt = new timezoneJS.Date("2012/04/10 10:10:30 +0000", 'Europe/London');
dt.setTimezone("Asia/Jakarta");
console.debug(dt); //return formatted date-time in asia/jakarta
