We consider time-dependent Lifshitz-type solutions in type IIB supergravity. The solutions describe a time evolution from Lifshitz spacetimes to AdS spaces. We argue the holographic relation of them to aging phenomena in condensed matter physics. The solutions have no time-translation invariance and possesses the dynamical scaling symmetry with z_c=2. In addition, the time evolution corresponds to slow-time (non-exponential) relaxation from non-equilibrium states to the equilibrium. We also discuss a mechanism of quantum quench to generate non-equilibrium states.
