I'm attempting to get a timezone of a user based on area code information that they provided. I discovered the following resource on maxmind:

<http://geolite.maxmind.com/download/geoip/api/php/timezone/>

I suspect that I could use this with another api that provides the state that an area code belongs to. I'm looking for a simple REST API that provides this info - or a robust scraping routine that achieve the same results. 

Thanks in advance!
