I have created this script for getting timezone by providing a particular latitude and longitude,

The idea is I crated timezone polygons for US and using Point in Polygon algorithm we can check the given latitude and longitude falls under which timezone.

Currently the sql dump I created for only USA, we can add polygons for additional countries.

for code:





  1. can it do reverse?

    meaning if I give a time zone can it identify all longitude’s with the same time zone?

    • Yes, the lat lng data stored as polygons, so we can return polygon points.
