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.
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.
