What is the source of the Arrow of Time?

Three sources are:
1. Evolution – goes in one direction only
2. Entropy – goes in one direction only, disorder, without new energy being added
3. The recession of the galaxies – apparently goes to expansion only, never to return to a singularity.
The above are discussed in G.W.Witrow’s book, “What is Time?.”
