reading tzdatabase for timezone definitions

Hi Experts,
I need to programmatically read timezone info.  For example, if given America/New_York, I want to get all the following information.

"America/New_York","EST","Eastern Standard Time","EDT","Eastern Daylight Time","-05:00:00","+01:00:00","2;0;3","+02:00:00","1;0;11","+02:00:00"

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You will find all necessary source code at the official page for the tz db: http://www.iana.org/time-zones - or a little more precise at http://www.iana.org/time-zones/repository/releases/tzcode2014b.tar.gz

See also http://en.wikipedia.org/wiki/Tz_database#Data_structure

The reference source code includes such a compiler called zic (zone information compiler), as well as code to read those files and use them in standard APIs such as localtime() and mktime().

Thank you JKR.  Is there any library APIs.   I am looking at the code for zdump but that seems very complicated....

I am afraid that 'zdump.c' really seems to be what you are looking for - however it's quite poorly documented :-/
