Since 3BSD is V7/V32 based - the TZ is sent in the kernel in sys/param.h
and compiled into it.
The system calls and user service calls in section 2 and 3 are seeded from
the value that the kernel returns.

The TZ environment variable was introduced in the PWB / SYS x  editions. It
was in PWB 3 and may have been
added before that.  I don't remember when the BSD stream picked it up - it
may not have been until after
the original /usr/group 1984 UNIX standard of the early 1980s - which I
codified it in their environ(5) definition.

The team in CSRG for BSD4.2 developed the time modern timezone database
that we see in most UNIX flavors at this time.
I don't remember where tzset(3) call was introduced, to be honest, it was
some time (in years IIRC)
after the TZ environment variable originally was created.
