DateFormatter

A wrapper around Intl.DateTimeFormat that fixes various browser bugs, and polyfills new features.

Introduction

DateFormatter is a wrapper around the native Intl.DateTimeFormat API. It exposes the same API, but works around several browser bugs and provides polyfills for newer features. These are currently:

A simple polyfill for the formatRange and formatRangeToParts methods for older browsers.
A workaround for a bug involving the hour12 option in Chrome and and the ECMAScript spec.
A workaround for a bug involving the hourCycle option in Safari.

See the MDN docs for full details on how to use the API.
