The most central feature is the global day/night map, with information about more than 10,000 locations around the world. Users can change their home location, and adjust the rate at which time passes, or manually set the time and date. These core features then tie in with applet-like plug-ins that display different information. How different? Several menus let you use the clock and map to view historic climate data, the positions of planets in the sky, or even the flight path of a jetliner traveling between two cities (and whether it'll be day or night at the destination).
These features fall within three main categories: astronomical, meteorological, and aviation. The astronomy tools let you find a past or future solar eclipse or follow objects in the sky on a time, date and at a rate governed by the day/night clock settings. Climate data isn't real-time, but historic; Regular updates continuously refresh the monthly averages. An alarm for prayer times rounds out the package.
