Negative entropy in turn is a measure of order, or information. The Second Law of Thermodynamics states that the entropy of the universe is always increasing. In otherwords, useful energy is being used up as randomness increases. Equilibrium is a state of balance. A probablistic interpretation would be a state of maximum disorder, i.e. entropy is maximized.
Time can only exist when thing happen such as when equilibrium is approached.
A system at equilibrium is in fact timeless since nothing further can happen. Order is maintained by the energy that flows through the life form .
