Hello everyone:
As almost all Continenal Chile just jumped back to UTC -4; I found there was a decree published last Thursday that will keep Magallanes region to UTC -3 "indefinitely"
Its only paragraph say:
"Nevertheless the aforementioned, the change of the Chile Continental Official time for Magallanes and Antártica Chile region will be extended indefinitely; and will be permanently set to GMT (sic) -3"
