This paper presents the equation for time and energy that executes four key attributes of time's flow regarding energy, namely, why time presents itself as unidirectional, why reality presents itself as a time-now phenomenon in between time-before and time-after in unidirectional time, why the laws of thermodynamics appear as they are in time-now, and why there is an "uncertainty" regarding the spatial location of elementary particles in time. This paper employs the equations of time and energy as presented in the lead-up papers by knitting those equations of time and energy together in addressing the four fundamental attributes of times flow regarding energy, concluding an event-horizon equation for time and energy as a unique mathematics for time separate to that of space, eliminating the reliance on spacetime theory as a singular mathematics, delivering space and time as two separate mathematics that can nonetheless be linked, surpassing the incompleteness problem as presented by Gödel, opening the door to a new cosmological model for space and time, all of such in upholding the data of all known physical phenomena in deriving all the relevant physical equations and constants.
