Note: The sudo mysql -e "SET GLOBAL time_zone = 'timezone';" command modifies the global time zone in MySQL for the duration of the current service uptime. Once the MySQL service is restarted, the settings return to the default (SYSTEM). For that reason, a much better option is setting the time zone by editing the MySQL configuration file.
