The Earth&Sun program shows the Sun Illuminated area of the Earth. It also displays:
- The latitude and longitude of an Earth location.
- The time zone at that location, based on only longitude not civil boundaries.
- The current time at that location based on the above time zone.
- The sunrise and sunset times, and day length at that location.
- Distance between two locations on the earth surface.
- Earth&Sun can also be a real time clock on the Palm V or a Palm Simulator.
