No, it is not, unless you count the gnomon as a lever and the dial bit as a wheel. I don't believe it is, though.

An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
a sundial is very simple to use mailny because it uses the suns rays however if it is night time the use of a sundial is no longer possible on the sundial it will have numbers on it and when the sun shines on it it will cast a particular shadow that shadow should line up with a number and then it will tell you the approximate time

The gnomon of a sundial is cut to a certain size depending on the latitude of the sundial's location. If the gnomon is not of the correct size, it can be compensated for by raising or lowering the lower edge of the sundial until all times are accurate. Calibration is fairly simple. Using a precise time measurement, when it is noon, go outside and position the sundial so the shadow of the gnomon is on noon on the sundial. Check it again at 1 pm, and adjust as needed.
