  We present Monte Carlo simulation results for the dynamical critical exponent
$z$ of the two-dimensional kinetic Ising model using a lattice of size $10^6
\times 10^6$ spins. We used Glauber as well as Metropolis dynamics. The
$z$-value of $2.16\pm 0.005$ was calculated from the magnetization and energy
relaxation from an ordered state towards the equilibrium state at $T_c$.
