no a sundial does not need to be reset because the shadow of the piece that measures the time is just following the way that the sun moves during the day the shadow reflects on how fast or how slow the sun moves.

The sundial fin needs to point directly towards true north in order for the sundial to accurately display the correct time based on the sun's position in the sky.
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.
To set your watch to local time using a sundial, first ensure the sundial is positioned correctly, with its gnomon (the vertical piece) pointing toward true north. Observe the shadow cast by the gnomon on the hour markings of the sundial, which indicate the time based on the position of the sun. Adjust your watch according to the reading on the sundial, accounting for any differences due to your watch’s time zone or daylight saving time if applicable. This method relies on clear sunlight and accurate positioning for best results.
I have a sundial in the garden.The sundial were the earliest form of clocks.
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.
The sun appears to rise in the East, move across the sky during the day and set in the West. A sundial has a pointy part which is called a gnomon. In the morning the shadow of its tip is in the West. During the day this shadow moves across the face of the sundial, and end up in the East. The gnomon is angled to take account of the latitude of the location and the sundial is graduated with marks which indicate the hours at which the shadow will fall at a particular place on the sundial.
