You are right and so am I. I looked at the source, and cron was 
already modified to use TZ. For me, I don't have to change the cron,
since we use Bell Labs Division 452 UNIX, and it seems our UNIX
is a little ahead of the official public release. I would *assume*
that bugs like that will eventaully find their way to a later release.
