Brazil & DST:

There are no DST related decrees after no. 4399 on the presidential decrees
lists for 2002 and 2003, up to decree no. 4842 from Sept. 18 2003.

I'd suggest: keep watching the latter page!

The information in
is a RECOMMENDATION from the Ministry of Mines & Energy.
Very likely a presidential decree will follow some time later.

>From the recommendation:

"recomenda-se a aplicação a partir do dia 19 de
Outubro de 2003 até o dia 14 de Fevereiro de 2004."

To me it is not clear what the start-ending times are.
Is there any proof that 0 h wall clock time and 24 h wall clock time are
used for _all_ time zones?
See also decree no. 2784 from 1913 about the definition of the "legal hour".
The first web-published decree mentioning the institution of a DST of 60
minutes with respect to "the legal hour" is no. 1636 from 1995.
