On Ubutu:
If you get 0.system for the version, this means you have the version that PHP shipped with. For a newer version, you must upgrade via the PECL extension (sudo pecl install timezonedb)

On Ubuntu:
If you get '0.system' for the version, this means PHP is using system version of timezone database. For a newer version, simply upgrade 'tzdata' package without installing any PECL extensions:
sudo apt update
sudo apt install tzdata
