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.
The sundial device was and is a very accurate tool of measuring units of time. The sundial devices uses the sun to pinpoint exactly what time it is because of where the shadow falls.
The compass on a portable sundial helps the user align the sundial accurately north-south, which is crucial for it to give accurate time readings based on the sun's position. By pointing the sundial's gnomon (the part that casts a shadow) towards true north using the compass, the sundial can accurately indicate the time.
A sundial uses light to measure time. Of course, it doesn't work well in the evening and on cloudy days.

A sundial may not work when it is placed in a location with limited sunlight, such as in a shaded area or during cloudy weather. Additionally, inaccuracies can occur due to changes in the sun's position throughout the year and variations in the sundial's alignment. Finally, improper calibration or design flaws can also lead to incorrect time readings.
