Dear IANA Team,

My name is Alexandre Dias and I'm a Data Scientist at a Brazilian Startup called Looqbox. As an R programmer and knowing that R uses the international standard IANA time zone rules. I would like to inform that the current Brazilian government changed daylight saving rules for "America/Sao_Paulo" timezone. This changes occurred this year and many devices are operating under the wrong hour of the day.

Usually, at this time of the year we had to advance our clock by one hour going from -03 GMT to -02. However, as I said, this is no longer the rules and the clocks must remain -03 GMT. Following there is a print of this phenomenon showing that R is display and returning the wrong time for my timezone:

The correct output should be "2019-11-04 13:25:27 -03". 

Given the problems that may arise from this kind of behavior, I kindly ask you to apply the changes I informed above as soon as possible.

Sincerely yours,

Alexandre Henrique Soares Dias
Data Scientist at Looqbox
