Use of tz database

Dear Messrs Olson and Eggert:


This is to request assistance with my research into a suitable time zone
database for use in updating commercial data products.

Tele Atlas North America, Inc. ("TANA") seeks to improve the content and
accuracy of time zone information within

its national and global, street centerline, proprietary database.


Since your website clearly describes the tz database as a public domain
database, I will want to proceed as if there are no restrictions on its
commercial use.

If restrictions do apply, please respond to that effect.  


TANA data analysts have reviewed a sample of your files. I am tasked
with relaying several technical observations / questions:

*	Is there a metadata file available? 
*	The purpose of the code is not clear. 
*	Can the code be 'tested'?
*	Will the code produce a list with state, county, and time zone
(as applicable for North America, of course)?
*	Does your naming convention NOT reference counties' association
with time zones?
*	Updates appear to be released 'as needed'. I believe the most
recent was Oct. 1, 2007//version h?  Is there an update schedule other
than as needed?


If the answers to these questions exist elsewhere, kindly point me to

Your time and attention to my request will be much appreciated.
