It's enshrined in POSIX but I believe it goes back earlier than that. http://pubs.opengroup.org/onlinepubs/9699919799/functions/tzset.html As I understand it, POSIX TZ offsets are the wrong way round because it was more convenient to omit the sign on the TZ offsets, and because Unix comes from America that meant no sign -> west, negative -> east.
