In physics, formulation of dynamics (whether classical or quantum) in terms of the energy Hamiltonian is very illluminating as it establishes certain fundamental relationships called canonical conjugate pairs e.g. Energy-time and Momentum-space. Concentrating on the first conjugate pair (because we are interested in time) shows that Energy and time are intrinsically connected. In otherwords, the existence of energy creates time and time must exist for energy to exist. This also tells us in no uncertain terms that time is a physical quantity which has a meaning only in a physical universe (because of its connection with energy). Time is not a metaphysical or philosophical quantity. It is generated in a physical universe in which energy exists and energy drives the system through changes through another physical property called time.

Time could be due to expansion of space. Time is slow where expansion of space is slow like around large masses. If total motion and forces within a mass is a constant then as the linear motion is increased the internal motion as well forces within that object slow which is then percieved as slowing of time. If we think of two objects in orbit around each other and imagine time slowing down then we should observe motion slow down as well as forces get weaker. Forces are part of time. Forces determine the arrow of time. Without forces time will be perfectly symetrical and lack any direction. Time may be just the presence of motion and forces.
