That is not the case. I acknowledge that the database format is not very
intuitive to read, but it *is* correct.

The Brazilian DST ("summer time" as we Brazilians call it) is correctly
coded in tzdata. Any system using a recent enough tzdata and the
America/Sao_Paulo timezone will be displaying the correct time (i.e.
UTC-2 during the DST).

The only problem right now is with America/Bahia and America/Araguaina,
since Bahia is not having DST anymore and Tocantins joined DST this
year. I sent a patch a couple days ago about this, and it should be
fixed in the next tzdata release.
