The 2010 Acre referendum consisted of a decision regarding maintaining the time zone change for the Brazilian state of Acre, as the state had an 1-hour difference from Brasília Time (UTC-03:00) in 2008, when the original time zone had minus 2 hours from Brasília.
History
In 1913, Executive Order 2,784 was signed,[1] which instituted the first time zones in Brazil. According to paragraph d, in joint interpretation with paragraph c, Acre and the area west of the line which connects the municipalities of Tabatinga and Porto Acre, was incorporated as part of the "fourth zone", characterized by GMT-5 (current UTC-05:00). Almost a century after the change, Federal Law no. 11,662 of 2008 was signed,[2] which, along with another change in the state of Pará (inserting it totally in the Brasília Regional Time), made the state of Acre and southwest Amazonas advance the time by one hour, to the UTC-04:00 time zone, on 23 June 2008.[3]
The referendum was held on 31 October 2010, on the same day of the second round of the 2010 presidential election.[6] The majority of the population decided to choose to return to the previous time zone, which had a 2-hour difference from Brasília Regional Time.[7]
The provisions of the referendum did not immediately commence due to doubts of the validity of the referendum by certain political elements[8] and pressure from TV broadcasters[9][10] that stalled its implementation for almost three years after the referendum had taken place. The change was finally approved by the Federal Senate committees in September 2013.[11]
As consequence, the Federal Law no. 12,876/2013 reestablished the previous time in Acre and southwest Amazonas, repealing the Federal Law no. 11,662/2008.[12] The regions covered by the change returned to the old time zone at midnight on Sunday, 10 November 2013.[13]
