Not always.  The 3B2 Sys V Rel 2.0.4 cron does not export TZ at all
even if it is told to do so in the manner mentioned above.  The System
V Rel 3.1 (maybe r3.0) properly exports TZ in the manner suggested.

With 3B2 Sys V Rel. 3.1, /etc/TIMEZONE is consulted by init to export
the proper time to getty and uucico and other friends.
