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

我在使用瞬间时区时遇到了麻烦。我加上这个答案是为了让其他人面对同样的问题。所以我有一个日期字符串2018-06-14 13:51:00来自我的API。我知道这是存储在UTC，但字符串本身并不说话。

我让moment timezone知道这个日期来自哪个时区:

let uTCDatetime = momentTz.tz("2018-06-14 13:51:00", "UTC").format();
// If your datetime is from any other timezone then add that instead of "UTC"
// this actually makes the date as : 2018-06-14T13:51:00Z

现在我想通过这样做将其转换为特定的时区:

let dateInMyTimeZone = momentTz.tz(uTCDatetime, "Asia/Kolkata").format("YYYY-MM-DD HH:mm:ss");
// now this results into: 2018-06-14 19:21:00, which is the corresponding date in my timezone.

这是为我工作在React本机应用程序。

import moment from 'moment-timezone'

function convertTZ(date, tzString) {
  const formatedDate = moment(date).tz(tzString).format()
  return formatedDate
}

export {convertTZ}

使用luxon库:

import { DateTime } from "luxon";

// Convert function:
const convertTz = (datetime, fromTz, toTz, format='yyyy-MM-dd HH:mm:ss') => {
  return DateTime.fromFormat(datetime, format, { zone: fromTz }).setZone(toTz).toFormat(format);
}

// Use it like this:
console.log(convertTz('2021-10-03 19:00:00', 'Europe/Lisbon', 'America/New_York'));

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`
);

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"
