goring, your Answer, Although Interesting, doesn't Address the Question.

Dr Ditto, Apparently, you don't Understand the Question.

Andrea L's Mention of Entropy Reveals she has a Deep Understanding of the Concept.

This is true for all action. The arrow of time is the direction of what we call forwards as a result of Chaos.......and the fact that there is more of it after every action, to that of before said action.

Entropy......I have included the link below.

The most basic definition of energy conservation is that energy can not be created or destroyed, only transformed. In a physical system depend on your reference frame, and the type of forces involved. From the mathematical point of view, the conservation law becomes from the symetry of time. This is because the physical quantities that describe a system are invariant under time translation. This is known as the Noether's theorem.

energy is a Phenomena whose value depends on the magnetude of the moving mass & the square of its velocity. So a mass loss indicates an increase of velocity and Kenetic energy.The scenario are interchabable .To change direction a mass loss is involved. So Energy is directional .
Time relates velocity a decreas in time indicates an increase of velocity and vice versa..
Basically the conservation laws should be lumped into one law ,called the LAW OF EQUILIBRIUM..What is one of the most important law is the conservation of time.

A conservation law, by definition, cannot have time dependence, so your question is meaningless.
