A sundial is a type of clock
The `Gnomon` is the part of the shadow clock, or sun dial, that casts a shadow onto the face from the sun, so that the time can be read.

-- Set the clock to the time at your home, and make a note of the longitude at your home. -- Go somewhere and take the clock with you. The clock must keep accurate time. -- Watch the sun. When the sun reaches its highest altitude above the horizon, note the time indicated on the clock. -- If the time on the clock is before noon, then you are east of your home. If the time on the clock is after noon, then you are west of your home. -- (15) times (the number of hours between noon and the time on the clock) is equal to number of degrees of longitude between your present location and your home. The touchiest part of this whole operation is the accuracy of the portable clock. If Leif Ericcson or Christopher Columbus had had anything as good as the cheap digital wristwatch that I bought from a street vendor a few years ago for 75¢ , the history of the New World's discovery would have been completely different.
there is no true relationship between distance from the sun and orbit time as some planets go revolves at a different velocity.

Sun dial and a clock?
a protable sun dial
Clocks consistently count precise units of time. A sundial determines the current solar time. The clock uses a regular, repetitive resonator, or oscillator, to mark off equal units of time, where as the sundial casts a shadow.
Because they were tired of unseeing the complex sun dial
When the sundial is properly alligned, the pointy shadow works just like the hour hand on a clock.
Sun Dial was created in 1990.
The astronomical clock located in Prague, Czech Republic was installed in the 1400's and is still functioning today. It has the zodiac dial which shows you the position of the sun and the moon in the sky. It has a calendar dial that represents the months of the year and it also shows you the apostles and death who move around the clock on the hour of every hour. It is important because the clock is one of a kind and was never able to be recreated.
