[2] The official time zone of Venezuela is determined by meridian 60° west of Greenwich, UK.
UTC−04:30 was formerly the official time zone in Venezuela from 1912 to 1965, when the government changed it in order to adopt meridian 60° UTC−04:00, which passes through Punta de Playa, Delta Amacuro State.
In 1965 the Republic of Venezuela Congress established meridian 60° W, near Punta de Playa in Delta Amacuro state, as official, since the previous one did not fulfill the international requirement for time standards of being based on integer differences with the GMT.
On 15 April 2016, President Nicolás Maduro announced that Venezuela would reverse Chávez's time change due to the shortage of electricity (the country's hydroelectric power has been hit by low water levels[1]) in Venezuela, with a return to UTC−04:00 which began on 1 May 2016 at 03:00:00.
