Why the moonrise and moonset time differs daily but the sunrise and sunset time are same?
You will get the correct answer, if you think on how you did conclude that sunrise and sunset times are same. If these were same, there will be no weather changes in the earth. If these are to be same, Call Issac Newton to help you tilt the Earth to 0 degree angle with respect to its vertical axis (passes through North to South Pole) and adjust the Earth speed and its distance from the Sun such that Earth always revolves in Ellipse of eccentricity 1 (Perfect Circular Path) around the Sun. Then, Sunrise and Sunset itself will give clear cut time helping your watch to be checked and adjusted. In fact, the question you or anyone raises should first be thought of as to how was this concluded to be asked and on based on what respect? Then you probably will get a pre-answer to your ultimate answer.
