A sundial is no good unless the sun is shining, and a shadow is cast.
A sundial relies on the position of the sun to cast a shadow, so on a cloudy day when the sun is obscured, a sundial would not be able to accurately tell time.
A sundial is no good unless the sun is shining strongly enough to cast a shadow.
A sundial is a round dial with a pointer for the sun. When placed correctly it will read the time of day.
Unfortunately, a sundial relies on the position of the sun's shadow to tell time, so it isn't possible to accurately tell time using a sundial on a cloudy day when the sun is obscured.

The pin on a sundial is called a gnomon. It casts a shadow onto the sundial's face, indicating the time of day as the sun moves across the sky.
A sundial is a type of clock that works by using the shadows cast by the sun. The position of the shadow tells the time based on the sundial's design.
A shadow clock, or sundial, tells the time of day using the position of the Sun. The sun casts a shadow from the sundial's style onto a marked surface of hours.
