Brazil's President Luiz Inacio Lula da Silva on Friday sanctioned a law approving a change in the western Amazon's time zone.
The law stipulates that clocks will no longer be five hours behind Greewich Mean Time (GMT) -- the time zone shared by Peru and Colombia -- in the state of Acre, in the southwest of the Amazon rainforest region, and several municipalities of the state of Amazonas.
On June 24, 46 municipalities will join states in the northern and midwestern regions of Brazil, which are four hours behind GMT, the same time zone as that of Bolivia and Chile.
The measure was taken in order to help television networks set their programming schedules and follow government policy that classifies programs according to people's ages, avoiding exposing children to adult content.
The country's official time -- the time zone adopted by Brazil's federal capital Brasilia as well as major cities like Riode Janeiro and Sao Paulo -- is three hours behind GMT.
Brazil will cover three time zones after the change. Clocks are two hours behind GMT in the archipelago of Fernando de Noronha, in the far east of the country.
