  The cosmic time dependencies of $G$, $\alpha$, $\hbar$ and of Standard Model
parameters like the Higgs vev and elementary particle masses are studied in the
framework of a new dark energy interpretation. Due to the associated time
variation of rulers, many effects turn out to be invisible. However, a rather
large time dependence is claimed to arise in association with dark energy
measurements, and smaller ones in connection with the Standard Model.
