time is something that applies to all things and Physics is the closest thing to a science that studies time - clocks themselves would fall under engineering

In a clock the source of power may be produced by a weight, a mainspring, or an electric current. In mechanical clocks, periodic lifting of the weight or tightening of the spring is needed. The motive force generated by the power source in a mechanical clock is transmitted by a gear train and regulated by a pendulum or a balance wheel. In such a clock the time may be reported audibly by the striking of a gong or chime and is registered visually by the rotation of wheels bearing numerals or by the position of hands on a dial; in electric or electronic clocks, time may be shown by a display of numbers.
A mechanical watch uses a coiled spring as its power source. As in spring-powered clocks, the watch transmits the spring’s energy to the hands by means of a gear train, with a balance wheel regulating the motive force.
The most precise timekeeping devices are atomic clocks, which are tuned to the frequency of oscillation between two energy states of certain atoms or molecules. Operation of the caesium-atom clock, used to define the basic unit of time of the International System of Units, depends on measurement of the frequency of the energy absorbed by a caesium atom in undergoing the change from a lower energy level to a higher one. These vibrations are unaffected by external forces.

Physics is the science concerned with the discovery and understanding of the fundamental laws which govern matter, energy, space, and time and explaining them using mathematics.
Since clocks are made from matter and energy, and measure time, they are part of the study of physics.

Clocks measure time, and time is a HUGE part of physics.

Not only is time important in Physics, but clocks have springs and pendulums and gears and may use electricity.

A clock is just an analogy of the motion of the earth.

Clocks have atoms...Clocks use energy
