Gnomon (γνώμων) is an ancient Greek word meaning "indicator", "one who
discerns," or "that which reveals." It has come to be used for a variety of
purposes in mathematics and other fields.

We have to define gnomon - as something perhaps common to all sundials.
It is information reflected off the device. Must a gnomon cast a shadow?

Color calibration was the primary function, however these sundials - which
are also on the previous Mars rovers - were in fact designed to also be
used to show time and season. Originally they were meant to be placed on
stationary landers. Since rovers can change direction and latitude, making

Hi dialers!
I thought I'd mention about a planned sundial which will be placed on a space
probe to the planet mars, Mars Surveyor 2001. Here are some links about it.

Toronto Astronomer, Andrew Yee, has advised:
The Planetary Society (founded by Carl Sagan) in Pasadena, Calif. is
soliciting
ideas on sending a sundial to Mars on the 2001 Mars mission.
