Setting the World Clock
The World clock tab allows you to set up a list of cities to easily check current times in other time zones with a quick glance.
Open the Clock app, then select the World clock tab.
Tap the New City icon
(at the upper-right corner of
the screen), search through the available cities, then tap the one
you want.
NOTE
The first time you access the World clock tab, a globe image is displayed in the middle of the screen. Tap it to add the first city to your list.
