  We investigate the statistics of single-mode delay times of waves reflected
from a disordered waveguide in the presence of wave localization. The
distribution of delay times is qualitatively different from the distribution in
the diffusive regime, and sensitive to coherent backscattering: The probability
to find small delay times is enhanced by a factor close to sqrt(2) for
reflection angles near the angle of incidence. This dynamic effect of coherent
backscattering disappears in the diffusive regime.
