import { safeTimezone } from "https://deno.land/x/complaindate@v1.0.1/utils/safeTimezone.ts";
Get a valid timezone name, adapted for the current user.
Falls back to the timezone of the local system if no valid timezone was found in the given string.
This is useful for sanitizing the current user's timezone preference into a
guaranteed valid timezone before applying any operations taking that timezone
as parameter. This avoids RangeError being thrown should the timezone be
invalid.
