That TZ syntax dates back at least to System III: = http://www.bitsavers.org/pdf/att/unix/System_III/UNIX_Users_Manual_Release= _3_Jun80.pdf (see CTIME(3C)), which did not support anything tzdb-related, and didn't = even support the more elaborate POSIX TZ syntax to include rules.

Full POSIX support - but not tzdb support, may have shown up in SVR3.2; = SVR4 had a tzcode-based implementation and shipped with the tzdb files.=
