Reported by a user through the CTRL+ENTER functionality in documentation:

Page: Zabbix appliance: "Frontend timezone is set to Europe/Riga (this can be modified in /etc/php-fpm.d/zabbix.conf);"

Request: would be great if default option "Europe/Riga" was already defined in zabbix.conf, this allow to change timezone without doubt on how to define.. if as an php_value or php base parameter.
