Time

Brazil has 4 time zones: Brazilian standard time is GMT-3; the Amazon time zone (Pará west of the Rio Xingu, Amazonas, Roraima, Rondônia, Mato Grosso and Mato Grosso do Sul) is GMT-4, the State of Acre is GMT-5; and the Fernando de Noronha archipelago is GMT-2. Clocks move forward 1 hr in summer for approximately 5 months (usually between Oct and Feb or Mar), but times of change vary. This does not apply to Acre.
