i want to know about the consequenses of the 2nd law of thermodynamics.microscopic particles obey newtons laws ,which are time invariant but wat about macroscopic?

Newton often wrote that time was invariant - that time was universal and flowed in a smooth continuum through out the universe. Technology and scientific observation, as well as our earthly experiences at the time, certainly could not dispute this.
Einstein disproved this - to a shocked audience of his peers (if it can be said he had any peers) when he formulated his theories concerning the effects of gravity, acceleration and relativistic speeds on the dilation of time as well as distance.
As an extra note, microscopic particles are not time invariant - at relativistic speeds, their "clocks" are slowed precisely as predicted by Einstein's equations.

Thermodynamics gives direction to the time by the entropy also it says time is variant it can never go back because entropy of a system should always in increase.Actually this is correct but according to classical physics in the study of relative velocity time is invariant for both the observerswhich is proven wrong by the relativity that time is always variable in all cases from an event to an event.
