SUNCLOCK 8
Sunclock is a program for Windows to show the local time around the world and the areas of the globe which are in night or day. In addition it shows the night sky and can be used to predict shadows at any location and any time of year.
City lights are visible at night-time. During the year the extent of the polar ice caps and the nature of the vegetation change to reflect the seasons.
Sunclock 8 can be used as a standalone program, or the world map can be used as a full-screen wall display, or as a screen saver (without password).
