o relógio está no fuso errado e quando eu tento mudar ele não salva
Select the timezone for the system. Look for the available timezones in /usr/share/zoneinfo/, then write it in the /etc/timezone file.
root #
ls /usr/share/zoneinfo
Suppose the timezone of choice is Europe/Brussels :
root #
echo "Europe/Brussels" > /etc/timezone
Please avoid the /usr/share/zoneinfo/Etc/GMT* timezones as their names do not indicate the expected zones. For instance, GMT-8 is in fact GMT+8.
