WorldClock Screen Saver Description
The WorldClock Screen Saver displays a high resolution map of the world that will accomodate even the highest resolution displays (up to 2000 pixels across). The day and night areas are clearly shown on the map (much the same as the Day/Night feature in WorldClock, but much bigger). You can also have the local time of up to twenty (ten in the trial version) cities displayed on transparent panels over the map; their times will be updated every minute. If you choose to display the clock, it will be updated every second.

The WorldClock Screen Saver can be configured to display the night area using a satellite composite image of the Earth's surface at night. The day area uses the regular map while the night area uses this new 'Night Lights' map. These 'Night Lights' are, of course, night illumination from our major metropolitan areas (street lighting, electric signs, etc.) which are clearly visible from space.

A typical WorldClock Screen Saver display with the day/night shadow in 'Night Lights' mode is shown below. This shot has been reduced to fit on this page and some detail has been lost. To do it full justice, you should see the original image (download the trial and see for yourself on your computer).

A snapshot of the WorldClock Screen Saver setup options screen is shown below.

As you can see from the screenshot above, the WorldClock Screen Saver can be customized in many different ways:
  • Whether to draw the night shadow on the map
  • The tint colour for the night shadow
  • The level of transparency for the night shadow
  • Whether to use a satellite image of Earth night lights instead of plain shadow
  • Whether to draw a clock on the map
  • The size, position, and colours of the clock
  • Whether to draw a calendar on the map
  • The size, position, and colours of the calendar
  • Whether to draw world lines (meridians) on the map
  • Whether to draw the Sun's overhead position on Earth
  • Whether to draw the Moon's overhead position on Earth
  • Whether to 'stretch' the map to fill your screen
  • You can pick up to twenty cities (ten in the trial version) from the place list on the right of this screen. (If you happen to choose more than twenty, the program will only save the first twenty selections.) The current times for all of your selected places will be drawn on the map at their appropriate geographic locations.
  • You have the option of having the time panels drawn transparently over the map, and you have control over the level of transparency.
  • You can choose the font and font size for the time panels.
  • You also have the option of allowing the time panels not to overlap. It is possible to select cities in close geographic proximity (although not very useful). This can, of course, cause the time display panels to overlap on top of each other. By selecting the no-overlap option, the program will try to re-organize the panels on the screen so that they do not overlap.
  • The current weather for your selected location (requires always-on Internet access).
  • Sun/Moon information.
