I think this whole discussion is built on the assumption that the client timezone and the application timezone are one thing and the same; and the server timezone is not relevant at all. If the app TZ is not the client TZ, then the app will need fixed. > Additionally, if you have your timestamp-with-original-timezone data > type, then you're going to need to recode every single > timestamp-handling function and operator to handle the new type. I have my doubts about that, and I hope not. These details haven't been discussed at all; I only started this thread to get community approval on cataloguing the TZs. -- Álvaro Herrera <alvhe...@commandprompt.com> The PostgreSQL Company - Command Prompt, Inc.
