Another possibility would be a separate environment variable that, if
defined, would request numeric abbreviations. This has the advantage (and
disadvantage) of providing for some system-level control: putting
	TZNUMERIC=1
(or whatever) in the system-wide startup file would buy numeric
abbreviations no matter what TZ value a particular user set up (unless, of
course, the user undid the TZNUMERIC).
