We consider an Ising spin glass chain at zero temperature. Introducing a time-dependence in the model by means of Glauber dynamics, we have calculated one-spin and two-spin correlation functions exactly. For example, we have found that if one starts at time t=0 with all the spins aligned, the magnetization evolves as . Our results are valid for a spin glass chain with an arbitrary symmetric and continuous distribution of nearest-neighbour interactions.
