on standard time year round. Chile Chile currently observes DST from the first Saturday in September to the first Saturday in April. In the past, DST was observed from the second Saturday in October to the second Saturday in March, but it has varied (see Time in Chile). In 2008, for example, the time was adjusted on Sunday, March 30, at 12 midnight. In 2010, because of an earthquake, DST remained in effect until April 3. In 2011, in order to prevent energy shortages after a dry summer, DST was first extended until April 2 and then until May 7. From 2011 to 2014, Chile DST started the first Saturday of September at 24:00, and ended the last Saturday of April at 24:00. DST was not observed in 2015 when the government declared that the country would remain on UTC-03:00 permanently. But on March 16, 2016, decree 253 modified the 2015 decision and restored winter time, except for the Magallanes and Chilean Antarctica Region which remains on UTC-03:00 permanently. It would last 90 days from the second weekend of May to the second weekend of August. Colombia From February 1992 until March 1993, Colombia suffered rolling blackouts of up to 10 hours a day due to a particularly strong El Niño season, which dried the reservoirs in hydroelectric plants in a country deriving 70% of its energy output from hydroelectric sources; consequently, the government decided to use DST to help save electricity. The experiment failed to deliver the intended results, possibly due to Colombia's low latitude, and the DST experiment was discontinued. Ecuador Ecuador's President Sixto Durán Ballén imposed daylight saving time in 1992 in an energy-saving effort. It was poorly received by the populace and did not last long. Falkland Islands DST (UTC−03:00) is generally observed from the first Sunday of September to the third Sunday of April. However, the Falklands remained on DST throughout 2011 and 2012. Paraguay Paraguay observes DST under decree 1867 of March 5, 2004. DST ends on the second Sunday of March and starts on the third Sunday of October. In 2007, DST started on October 15, 2006, and ended on March 11, 2007. In 2010, Paraguay changed its own DST rules because of the energy crisis, ending DST on the second Sunday in April, a month later than previous years. The start date remains unchanged. Uruguay Beginning in 2004, Uruguay began to observe
