phone-number

I have a (potentially international) phone number. It may or may not have a country code prefix. Does anyone know of a database that will help me map phone number => time zone? I would even just like to map phone number => country, since I can probably create country => time zone by scraping existing data on the web. This is a more complicated problem than it looks; for example, how do I know if it's a US-based number -- e.g. is it a USA area code, or an international country calling code?

Any language is fine; I can port it.
