如何在 javascript 中获得所有时区的列表

小开

The react-intl library's time zone functionality is provided exclusively by the ECMAScript Internationalization API features that are integrated into the browser.

While IANA time zone support is part of this spec, it currently only covers two scenarios:

Formating a Date object to a string, converting to a specific time zone in the process.
Determining the user's local time zone identifier.

Unfortunately, there is no function defined by the spec for enumerating the list of available time zones.

Additionally, note that support for the two functions it does have is currently limited to a handful of browsers. It will likely be quite some time before these capabilities can be depended upon. The ECMAScript Compatibility Table shows which browsers are supported. Under DateTimeFormat you'll find "resolvedOptions().timeZone defaults to the host environment" and "accepts IANA timezone names" that track these features.

For the future searchers, it's possible to get a list of all timezones using moment-timezone.

import momentTZ from 'moment-timezone';


const defaultTimeZone = momentTZ.tz.guess();
const timeZonesList = momentTZ.tz.names();

I realize my answer is late, but if you are using Intl and you care about time zones, and you're facing the web, then you are almost certainly going to need https://github.com/yahoo/date-time-format-timezone. Since you will have this in your project anyway, you can retrieve the time zone data from inside the polyfill even if you're not using the polyfill.

Everyone is using the IANA database so you should get consistent results.

I recently created an array containing all timezones and found that a couple of official timezones were missing from Chromium 71.0.3578.98.

You can see that array in this comment of the bug I reported. For convenience, I've included the array below:

{
let strTime = date.toLocaleString("en-US", {timeZone: `${timeZone}`});
console.log(timeZone, strTime);
});

If you're like me, in wondering why there are so many timezones, check out this question.

UPDATE 2022-06-08:

If you only need a full list of time zones that your environment supports, you can now acquire that array using Intl.supportedValuesOf(), like this:

let ary = Intl.supportedValuesOf('timeZone');

Whether that list is complete or not, will depend on your environment.

In the snippet below, I replace that array (from the first snippet) with Intl.supportedValuesOf('timeZone'):

var aryIannaTimeZones = Intl.supportedValuesOf('timeZone');


let date = new Date;
aryIannaTimeZones.forEach((timeZone) =>
{
let strTime = date.toLocaleString("en-US",{timeZone: `${timeZone}`});
console.log(timeZone, strTime);
});

Here's a comparison of the custom array versus Intl.supportedValuesOf('timeZone'):

Running the comparison above produces different results in each environment/browser I try. The latest Firefox reveals that numerous time zones have been added to the spec since I originally created that static list. However, other environments (I try) are still missing official time zones that were indeed included in that old list.

As of Jul 5th 2022, despite what's reflected on on caniuse or MDN, I see Intl.supportedValuesOf('timeZone') working in the latest:

Chromium
Firefox
Node (v.18.4.0)

If Intl.supportedValuesOf('timeZone') isn't working in the snippets above, for a browser you're targeting, feel free to include a URL to that issue's bug-tracker in the comments below.

I did not find the list of time-zone through browser javascript so created array of timezone list and used it.

Option 1

Till Dec 25, 2020 in JAVA 11 ZoneRulesProvider.java

Create array/collection and use this without external library

I found 600 sorted TimeZone

I too needed to have a complete time zone list with preformated data like:

{
name: "America/Los_Angeles",
alternativeName: "Pacific Time",
group: ["America/Los_Angeles"],
countryName: "United States",
mainCities: ["Los Angeles", "San Diego"],
rawOffsetInMinutes: -480, // "raw" time zone offset, when there's no DST in place
rawFormat: "-08:00 Pacific Time - Los Angeles, San Diego",
currentTimeOffsetInMinutes: -420, // "current" time zone offset, this is why getTimeZones() is a method and not just an object: it can only work at runtime
currentTimeFormat: "-07:00 Pacific Time - Los Angeles, San Diego",
}

Since I could not find a good list that would also be maintained, I created an npm package for it: https://github.com/vvo/tzdb/. The list of time zones is automatically updated when there are changes (like new time zones).

You can then use https://github.com/moment/luxon if you need to manipulate dates with time zones.

The list of time zones is grouped to reduce the number of time zones. We do grouping only when: same country AND same offsets (DST, non DST).

This basically gives you a time zone list that is very close to the one from Google Calendar.

Good luck!

The marked answer doesn't seem to work for the Pacific/Honolulu timezone.

I've made another function that worked for that:

function getTimezoneOffset(timeZone) {
const now = new Date();
const tzString = now.toLocaleString('en-US', { timeZone });
const localString = now.toLocaleString('en-US');
const diff = (Date.parse(localString) - Date.parse(tzString)) / 3600000;
const offset = diff + now.getTimezoneOffset() / 60;
  

return -offset;
}

Usage example:

const offset = getTimezoneOffset('Pacific/Honolulu');


console.log(offset); // output: -10

I have updated the timezone list in the parent and child.

I realize my answer is late, but I just created a package about this:

https://github.com/UltiRequiem/timezones

import {
randomTimeZone,
timeZones,
} from "https://deno.land/x/timezones/mod.ts";


console.log(`My timezone is ${randomTimeZone()}.`);


const date = new Date();


for (const timeZone of timeZones) {
console.log(timeZone, date.toLocaleString("en-US", { timeZone }));
}

Supports

Node.js

https://www.npmjs.com/package/@ultirequiem/timezones

Deno

https://deno.land/x/timezones

Browser

https://github.com/UltiRequiem/timezones#browser

Just for timezone list, adding a big package like moment is not recommended. Adding moment package will increase your application size and will slow down your application performance. Here is the latest timezones array

In react there re multiple ways to do so, but you can get all timezone using countries-and-timezones library.

first import the library:

import TimezoneCountries from "countries-and-timezones";

after importing, paste below code snippet to get list of all timezones.

export function getAllTimezones() {
const allTimezones = Object.values(
TimezoneCountries.getAllTimezones({ deprecated: true })
).map((list) => ({
value: list.name,
label: `${list.name}`,
}));
return allTimezones;
}

you can also get country name and utc offset by adding following lines

list.countries //to get country names in which timezone is used
list.utcOffsetStr //to get UTC offset
