get-timezone-name

Small package that returns the runtime timezone name.

Returns the IANA timezone name when available (for example America/Los_Angeles). If the runtime does not provide an IANA name, the package falls back to process.env.TZ and then to a computed UTC±HH:MM offset.

Installation

npm install get-timezone-name

Usage (CommonJS)

const getTimeZoneName = require("get-timezone-name");
console.log(getTimeZoneName());

Usage (ESM)

import getTimeZoneName from "get-timezone-name";
console.log(getTimeZoneName());

Behavior & compatibility

• Primary source: Intl.DateTimeFormat().resolvedOptions().timeZone (IANA name).
• Fallback 1: process.env.TZ (if set).
• Fallback 2: computed UTC±HH:MM derived from new Date().getTimezoneOffset().

Note: Some Node builds (minimal ICU) or older environments may not provide timeZone in resolvedOptions() — the fallback ensures a usable string is returned.
