import { supportedCanonicalTimezones } from "https://deno.land/x/complaindate@v1.0.1/mod.ts";
Get all canonical timezones that are supported by the browser or runtime, or an empty array if the list is not available.
This is useful for populating an HTML
<datalist id="availableTimezones">
with all relevant timezones, enabling an ordinary
<input type="text" list="availableTimezones">
to become an autocomplete "combobox" for the user to select from.
See datalist documentation on MDN
for details and examples.
Most browsers and runtime systems expose this list of 400+ timezones since March or April 2022. See compatibility data on MDN for details.
