Original close reason(s) were not resolved

Intl.supportedValuesOf('timeZone')

Above code will give list of all time zone in en-US like below

["Africa/Abidjan", "Africa/Accra" , "Africa/Addis_Ababa", ...]

Is there way to get list of all time zone in desire language.

• Mark Rotteveel: Those names are identifiers, not localized names.

Above code will give list of all time zone in en-US

It looked like you think en-US (the locale) would select the time zone identifiers for that locale.

locale and timeZone are not related. You can for example format a date in the locale en-US for timeZone Asia/Shanghai.

const myDate = new Date(`2000年01月01日`);
console.log(
 [myDate.toLocaleString(`en-US`, {timeZone: `Asia/Shanghai`}),
 myDate.toLocaleString(`zh`, {timeZone: `Asia/Shanghai`}),
 myDate.toLocaleString(`en-CA`, {timeZone: `Pacific/Auckland`}),].join(`\n`)
);

So, afaik using JS Date, it is not possible to retrieve a time zone from a locale.

In this Stackblitz project I have related a number of cities to their time zone, using world-timedate.com which was quite cumbersome.

Here is a library I created to make working with JS Dates a bit more easy. Maybe it's useful.

• VLAZ: "So, afaik using JS Date, it is not possible to retrieve a time zone from a locale." No, you can't get a time zone name from a locale. But you can get a localised time zone name from an IANA time zone name (which Intl.supportedValuesOf('timeZone') provides) using Intl.DateTimeFormat jsbin.com/tereyituzi/1/edit?js,console However, you can't get the IANA name localised. These are the options for the time zone name.
