Local magnetization curves at different times, extracted from high-temporal resolution magneto-optical measurements in Bi_(2)Sr_(2)CaCu_(2)O_(8+δ), demonstrate the absence of the second magnetization peak at short times, its appearance at longer times, and the movement of its onset toward higher-induction fields approaching the thermodynamic vortex order-disorder transition field. We relate this phenomena to metastable disordered states induced by edge contamination for inductions in the vicinity of the order-disorder vortex phase transition. We show that the time evolution of the second magnetization peak is governed by the relaxation times of the metastable disordered vortex states.
