  We investigate the dynamical behavior of the Sherrington-Kirkpatrick mean
field model of spin glasses by numerical simulation. All the time scales tau we
have measured behave like ln(tau) propto N^epsilon, where N is the number of
spins and epsilon \simeq 1/3. This is true whether the autocorrelation function
used to define tau is sensitive to the full reversal of the system or not.
