esripdx / Timezone-API

Example

curl "http://api.example.com/timezone?latitude=45.5118&longitude=-122.6433"

or, if you don't like query string parameters:

curl http://api.example.com/timezone/45.5118/-122.6433

Example response:

{
  timezone: "America/Los_Angeles",
  offset: "-07:00",
  seconds: -25200
}

Setup

You will first need to create a PostGIS-enabled database.

Set up your database config in config.php, then run import.php which will create the timezone table and import all the data from the tz_cities.txt file.

After configuring Nginx or another web server, you will be able to make requests like the example above.

Nginx Config

server {
    listen 80;
    access_log /var/log/nginx/timezone.log main;
    error_log /var/log/nginx/timezone.log notice;

    root /web/Timezone-API;

    location / {
        try_files $uri /index.php?$query_string;
    }

    location ~ \.php {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        include fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}
