TZ changes for Brazil for 2003/2004

[Paulo Alexandre Pinto Pires]

Dear sirs,

Attached are my diffs to tzdata2003c for the just-released rules for
Brazilian summer time 2003/2004.

Since this year two states that traditionally obeyed summer time are
no longer doing so, I had to create two new cities, namely Salvador
and Campo Grande, for the states of Bahia (BA) and Mato Grosso do
Sul (MS).

Hoping to have helped,

 # The latest decree listed above says that the following states observe DST:
 # BA, DF, ES, GO, MG, MS, MT, PR, RJ, RS, SC, SP, TO.
 #
-# For dates after mid-2003, the above rules with TO="max" are guesses
-# and are quite possibly wrong, but are more likely than no DST at all.
+# Another change for 2003/2004 (not in http://pcdsh01.on.br/ yet -- ON has
+# been lagging behind lastest decrees; this information was found in
+# http://oglobo.globo.com/online/pais/110274614.asp).
+#
+# One major difference is that the state of Bahia (BA) will not have summer
+# time this year, together with Mato Grosso (MT) and Tocantins (TO).  Summer
+# time will be effective only for the southern, southeastern and two of
+# central-western states, and for the Federal District.  Namely, summer time
+# includes only RS, SC, PR, SP, RJ, ES, MG, MS, GO and DF.
