Some time ago I tried do set up a similar TZ variable for my location
(Southeastern Brazil) and found that it does not work for the Southern
Hemisphere. Apparently the software accepts only summer time (DST)
beggining in a month smaller than the ending month.

Maybe the software author doesn't know that in places like South America,
New Zealand, Australia and part of Africa summer goes from December to
March!

So I have to change my TZ variable whenever summer time starts or ends.
