Quickly find the name of a time zone for a latitude and longitude without relying on a web service.
NearestTimeZone.to(41.85, -87.65)
=> "America/Chicago"
On a whatever MacBook Air, the time to lookup a single time zone is ~0.000030 seconds. Fast.
The city data is based on the GeoNames cities1000.zip data. To compress the size of the gem, the latitudes and longitudes were rounded to one decimal point of precision.
The Kdtree gem is used to make the search so fast.
The kdtree and the cities are loaded into memory when the gem is loaded. If you'd like to make that faster, run rake nearest_time_zone:dump and the load time should drop significantly. The cities, time zones and kdtree will all be persisted to the file system when run that rake task.
