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
}
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.
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;
}
}
