The Sundial

(Hint: Run WorldClock Lite and refer to the screen while reading this documentation page
from a printout.)
__________________________________________________________________________

Choose Sundial from the WorldClock Lite menu in the menu bar at the top of the
screen.

The Sundial screen shows a rectangle with a simulated fencepost at the center. If the 
sun is above the horizon, the shadow of the fencepost is graphically displayed. If you 
let the program run all day, the shadow will move in the same pattern that a real shadow 
would.

When the sun goes down, the shadow disappears, and the surrounding rectangle goes 
through deeper shades of gray until it becomes completely black when the sun is more 
than 18° below the horizon.

The Animate button on this screen will allow you to speed up the movement of the 
display to have 24 hours go by in a couple of minutes. After clicking on the Animate 
button, it will change to a Real Time button.  Click on the Real Time button to stop 
the animation and return to the correct display for the current date and time.  While the 
display is animating, you may temporarily "freeze" the movement by clicking on the 
digital clock panel at the lower right of the map.  To resume animation, click on the clock 
panel a second time.  

To the right of the sundial rectangle, the text readout gives the azumuth (degrees clock-
wise from true north) and the altitude (degrees above the horizon) of both the sun and 
the moon. By selecting a date on one of the "Calendar" screens, and animating the sundial
to the desired time and then freezing the display, photographers can forecast the positions
of the sun and moon for a "shoot", or can determine the best times or locations for a
"shoot".
