README

This is the JavaScript version of github.com/bradfitz/latlong.

The Go code in this directory generates the latlong.js, which has the
timezone location data embedded. To generate it again run `make`.

See https://plus.google.com/u/0/+BradFitzpatrick/posts/XVyy1bAzkZd
for some background on the original Go version.

Overview

Package latlong maps from a latitude and longitude to a timezone.

It uses the data from http://efele.net/maps/tz/world/ compressed down to an internal form optimized for low memory overhead and fast lookups at the expense of perfect accuracy when close to borders. The data files are compiled in to this package and do not require explicit loading.
