Ways to use a full-screen clock

• A wall clock for offices, classrooms and waiting rooms

• A large, readable clock for anyone who finds small clocks hard to see

Where does the time come from?

The clock reads the time from your device’s system clock and updates every second. Most phones and computers set their clock automatically from internet time servers, so it is normally accurate to within a fraction of a second. If the time looks wrong, check your device’s date, time and time zone settings.
