i tried using the wiki to fix it and now it has the correct timezone. realpath answers “/usr/share/zoneinfo/America/Sao_Paulo”
though the xfce time still shows that the pc time is 16 minutes late. date command does the same. (exemple: phone shows 15:16, which is the actual time, while pc shows 15:00)
though i dont live in sao paulo, it is just a little north of here and should be in the same timezone. also, when i installed the OS with that timezone, it showed the correct time.
