Daylight saving time in Brazil changes every year.
http://pt.wikipedia.org/wiki/Anexo:Lista_de_per%C3%ADodos_em_que_vigorou_o_hor%C3%A1rio_de_ver%C3%A3o_no_Brasil
(Sorry, I couldn't find a version in English. But the page shows it changes
every year).
For my experience, DST information in Ubuntu is much more accurate than it is
in Windows. I remember when I was a Windows-user that it ALWAYS missed the DST.
The package tzdata in Ubuntu is updated once/twice per year. This year it was
already updated at least once. And it is right in saying that the standard time
started 15 Feb 2009 (wikipedia confirms it). It is not right that it will end
in 31 Dec, but it will only end next year so I suppose it is ok, and probably
there will be another update next year correcting it.

By the way, I wanted to ask: how is DST in wine updated? Just when someone
sends a patch to do it?
If that's the case, maybe wine should "trust" more in the native OS and winecfg
should have a option to the user select the timezone. If the info in the
registry diverts, it is automatically updated. It would also remove complexity
of some time-related functions.
I could write such a patch, if you help me review it.
