free web service returning city names, city codes and time zone

Question

Do you know a web service that's able let's say get a full list of cities in the world with names, short names like PAR for Paris and time zones?

Or at least query by city name: Paris -> timezone=+02:00, abbrev=PAR

Also, what I see here: http://www.earthtools.org/webservices.htm#timezone

offset The number of hours offset from UTC disregarding any correction for daylight saving time.

That's not a desired result. Of course we need this correction!
