 Some [browsers do not support arbitrary time zone ](http://kangax.github.io/compat-table/esintl/) in Intl.DateTimeFormat API (becuase its optional as per [ECMA-402 standard](https://www.ecma-international.org/ecma-402/1.0/#sec-6.4)). This polyfill is only to bring this support. Polyfill contains historical timezone data, CLDR data & tiny code to polyfill this support.
