  We study a model for the dynamics of vortices in type II superconductors. In
particular, we discuss glassy ``off equilibrium'' properties and ``aging'' in
magnetic creep. At low temperatures a crossover point is found, Tg, where
relaxation times seem to diverge a' la Vogel-Tamman-Fulcher. Magnetic creep
changes by crossing Tg: above Tg power law creep is found asymptotically
followed by stretched exponential saturation; below Tg the creep is logarithmic
and vortex motion strongly subdiffusive. In this region violation of time
translation invariance is found along with important dynamical scaling
properties. A thermodynamic glassy transition point can be found at a lower
temperature Tc.
