Dear Friends, PLEASE! As a new member of this listing, I think it's a little bit hard to understand how to use the TZ database, I tried to read all files, but I don't get the right information. Somebody could tell me about: 1. Is there some readme files explaining how to use the tz code and database? 2. Is there some demo program or tutorial about TZ ? 3. Is there another sites about the TZ database? PLEASE! I really need to understand TZ. I know C language very well. I just couldn't figure out how to use TZ. I would like to build a program that shows by country the TZ and DLS info. Somebody pick a country and some date, and the program will say if that time was in DLS and what TZ was that time. Thanks in advance! Floriano Caldeira floriano@ilhanet.com.br
