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.
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.
Not usually unless the sun comes out for short periods of time so you can see what time it is.
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.
A sundial is not accurate when it is cloudy, rainy, or at night when there is no direct sunlight to cast a shadow. Additionally, if the sundial is not properly calibrated for its location or if it is moved, it may not accurately tell time.

A sundial uses light to measure time. Of course, it doesn't work well in the evening and on cloudy days.

the sun casts a shadow onto the sundial and the shadow tells the time of the day.
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.

The raised arm of a sundial that indicates the time of day by its shadow is the gnomon (NO-mon). A sundial has but one arm, what do you mean by secondary arm?
gnomon
The biggest issue is that they require the sun. Which means they are unusable 50% of the time. And then they don't work when it is raining or cloudy. And they have to placed where the sun hits them, so it is not always convenient to put them near the house.
A sundial can be used throughout the year, but its accuracy may vary depending on the season and the latitude of the location. Sundials are most accurate during the equinoxes, when the sun's path is directly overhead at noon. In locations closer to the poles, the accuracy of a sundial may decrease during the winter months when the sun's path is lower in the sky.
