Intl.Locale.prototype.getTimeZones()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The getTimeZones() method of Intl.Locale instances returns a list of supported time zones for this locale.
Note:
In some versions of some browsers, this method was implemented as an accessor property called timeZones. However, because it returns a new array on each access, it is now implemented as a method to prevent the situation of locale.timeZones === locale.timeZones returning false. Check the browser compatibility table for details.
Syntax
getTimeZones()
Parameters
None.
Return value
An array of strings representing supported time zones for the associated Locale, where each value is an IANA time zone canonical name, sorted in alphabetical order. If the locale identifier does not contain a region subtag, the returned value is undefined.
Note:
The standardization of Temporal requires browsers to always return the primary identifier in the IANA database, which may change over time. See time zones and offsets for more information.
Examples
Obtaining supported time zones
List supported time zones for a given Locale.
const arEG = new Intl.Locale("ar-EG");
console.log(arEG.getTimeZones()); // ["Africa/Cairo"]
const jaJP = new Intl.Locale("ja-JP");
console.log(jaJP.getTimeZones()); // ["Asia/Tokyo"]
const ar = new Intl.Locale("ar");
console.log(ar.getTimeZones()); // undefined
