latlong

README

This is a Go package which maps a (lat, long) to a timezone which forked from bradfitz/latlong.

Since the data source tz_world.zip is no longer maintained, we use another OSM-based map timezone-boundary-builder instead.

The z_gen_tables.go was generated by 2018d release timezones.shapefile.zip.

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.
