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?

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

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);
无耻地窃取自:http://www.techrepublic.com/article/convert-the-local-time-to-another-time-zone-with-this-javascript/6016329
/**
* function to calculate local time
* in a different city
* given the city's UTC offset
*/
function calcTime(city, offset) {
// create Date object for current location
var d = new Date();
// get UTC time in msec
var utc = d.getTime();
// create new Date object for different city
// using supplied offset
var nd = new Date(utc + (3600000*offset));
// return time as a string
return "The local time in " + city + " is " + nd.toLocaleString();
}
这个函数通过提供城市/国家的名称和偏移值来计算时区值
快速和肮脏的手动换时和返回:
return new Date(new Date().setHours(new Date().getHours()+3)).getHours()
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"
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);
