In this paper I continue with the elementary particle Dark Matter halo model. The first few sections will shortly repeat the basics of this model. In section II I take a better look at the modified Newtonian potential as a consequence of the changed source mass. In section VI the effect of the modified potential on Einstein lensing is touched briefly. In sections VII and VIII the order stored in the frequency gauge of the de Broglie time devices in the outer galactic disks due to Dark Matter is related to entropy. The study of order stored in frequency synchronized or desynchronized time devices is called chronodynamics and this is added to the thermodynamics part of entropy. We show that in the inner galactic range thermodynamic entropy dominates chronodynamic entropy but that in the outer flat rotation curve part of the galactic disks the chronodynamic entropy dominates by far. We show that the chronodynamic entropy of a galaxy is lowest in its outer fringes and highest in its luminous center. This creates an inward entropic force and that is how the Dark Matter halo, through the intermediate of chronodynamic entropy, stabilizes galaxies. The frequency gauge of the de Broglie elementary time devices in the outer range of galactic disks creates a sort of a gauged time bubble in a cosmic time sea, a gauge regulated by the BTF relation. In the last section we relate this galactic gauged time bubble to GR as a reference frame independent theory of gravity.
