System Date & Time
Here you can set the preferred Timezone and clock type for the system. This is just a technical matter, and more specific timezones for different locations will be set in "Locations" in the "General" tab.
This is where you add all your different locations.
Ex: You have 3 buildings with 3 receptions in city X in country X, you also have 1 building with a reception in city Y in country Y, you will then need to add 4 locations. see picture below.
