EarthWatch

EarthWatch (for Windows) displays a graphical world clock with dynamic map image of the world showing the day and night areas, a sundial, and an almanac information panel featuring sunrise/sunset times and much more -- all in real-time or time-lapse animation.

EarthWatch is informative, educational, and beautiful, and includes the following features:

Option to choose from two map types: political or natural.

Graphical presentation of the day and night areas of the earth.

Selection of any date from the year -4000 to + 4000.
