Even that shouldn't be necessary, in S5R3.1 and later (maybe even
S5R3.0), since:

	1) as you noted elsewhere, "init" reads "/etc/TIMEZONE" and sets
	   up the environment from it;

	2) "login" - at least in the 3B2 source version of S5R3.1 -
	   preserves the value of "TZ".

If it *is* necessary, somebody screwed up badly.
