Make sure you won't wake your parents up when you call, or check the time for your important conference call in a few days. Within the app you can add as many favourite cities as you like from a huge database that includes cities all over the world. At any time you are able to select one of your cities, and set the time for that location, allowing you to see the relative time in all your other cities. When you're done, it's easy to reset to the current time. Ideas for features or have an issue? Email [email protected] or reach us on Twitter @zones_app
