The ATIV Clock app allows users to select a custom time zone and then see that time through a Live Tile on the Start screen, taking advantage of Windows Phone 8.1 ability to update Live Tiles in real-time, and also allows adding calendar events based on the time in different cities and countries. The app is currently available on the Windows Phone Store; Samsung will likely roll out the Windows Phone 8.1 update very soon, unless it intends to let the ATIV Clock app remain useless and inaccessible to any Windows Phone device out there.
