Brazil has adopted Standard Time all year, and it's been so good!
Please, Standard Time is preferred globally, but don't confuse the topics.
Then a couple of years ago the north and northeastern parts of the country, which are closer to the equator, stopped observing daylight savings time.
Finally, this year the president passed an executive order that abolished daylight savings time for the whole country. If it had not been canceled, this year's daylight savings time would have started two weeks ago. There was a brief confusion because some people's cellphones didn't update the time zone database correctly and switched to daylight savings time even though they should not anymore.
