Address allows you to set the address of the organisation, the language that is used in the system and the time zone that is used in the system. This can be changed in the 'Settings' section of the dashboard.
By default the language is set to English and the time zone is set to (UTC+00:00) Dublin, Edinburgh, Lisbon, London.
If you change the time zone this will impact reports and show the time that users accessed training according to the time zone that the system is set to.
