Know your iPhone4: Setting Up Clocks for Different Time Zones

Start at the Home screen and tap on the Utilities folder, then tap on Clock. Tap on World Clock at the bottom-left corner of the screen. By default, the World Clock screen shows the current times in Cupertino, California and New York. To delete a clock (we’ll delete Cupertino’s clock here), tap the Edit button in the upper-left corner, and a red circle with a – (minus sign) appears before each city. Tap the red circle for the one you want to delete and a Delete button appears on the right. Tap Delete and it’s gone (the clock— not Cupertino itself). To add a new city, tap the + (plus sign) button in the top-right corner to bring up a city search field and keyboard. Type in the city you want to add (in our example here, I typed in London. Actually, I just typed in “lon” and London, England, appeared in the list). When your city appears in the list, just tap on it and it’s added as a clock. To add more cities, just tap the + button again.
