In this contribution to the proceedings I carried out the full chronological line in numerical simulations to give clear evidence against a phase transition in shortrange spin glass models at least in two dimensions. Furtheron I consider the observation time necessary to obtain equilibrium states at low temperatures — it exceeds 100 years. Then I provide the theory of a new phenomenon: the time dependent specific heat. It is hoped that this effect helps experimentalists to provide convincing evidence in favour or against a transition.
