This is one of those news items you don’t read about every day. Yesterday Brazil lost, as a result of a government decree, one time zone. The change affects the states of Acre (it has now one hour less than Brasilia), Amazon (it now has just the one zone for the entire state) and Pará (with just the one time zone, the same as Brasilia).
From now on, Brazil will only have three time zones. Regions west and centre will have one; Brasilia and regions north-east, south and south-east will have the second one; and Fernando de Noronha will have the third time zone.
