HOW TO Use the Clock app’s world clock

1 Add a world clock

Open the Clock App, and click on the World Clock tab at the top. Your current location’s time zone is already shown. To add a new world clock, click the ‘+’ icon (top-right). Type the name of a city in the Search field.

2 Add its time zone

When you’ve found your city, click on it to add its time zone to the Clock app. The light and dark sections of the world map show the areas currently in daytime or night-time, as do the white or black clock faces.

3 Delete a clock

To delete a world clock from the Clock app, move the pointer over its clock face and a ‘X’ appears in the topleft corner of its window. Click on this cross and that time zone disappears. You can add it again later.
