Two sets have only small parts of Brazil, and don't use DTS [they are at GMT-2 and GMT-5]. Two other sets are at GMT-3 and GMT-4, and don't apply DST. Two other sets are at GMT-3 and GMT-4, and apply DST [turning to GMT-2 and GMT-3]. Alberto Monteiro @ GMT-3 except in Spring or Summer when it's GMT-2 [this message was written at 11:55 local or 14:55 GMT]
