Surgically polyfills timezone support in Intl.DateTimeFormat API
![Build Status][] ![NPMRel][] [Build Status]: https://travis-ci.org/yahoo/date-time-format-timezone.svg?branch=master [NPMRel]: https://img.shields.io/npm/v/date-time-format-timezone.svg
Some browsers do not support arbitrary time zone in Intl.DateTimeFormat API (becuase its optional as per ECMA-402 standard). This polyfill is only to bring this support. Polyfill contains historical timezone data, CLDR data & tiny code to polyfill this support.
- install
`npm i date-time-format-timezone`
- nodejs
`require('date-time-format-timezone'); // polyfill is ready`
- browser
`<script src="build/browserified/date-time-format-time-zone-complete-min.js">`
or
<script src="build/browserified/date-time-format-time-zone-no-data.js">
<script src="build/browserified/data/locales/locale-en-US-POSIX.js">
<script src="build/browserified/data/metazone.js">
<script src="build/browserified/data/timezones/tzdata-america-los_angeles.js">
This polyfill can add this support.
