  The measured distribution of the single-channel delay time of localized
microwave radiation and its correlation with intensity differ sharply from the
behavior of diffusive waves. The delay time is found to increase with
intensity, while its variance is inversely proportional to the fourth root of
the intensity. The distribution of the delay time weighted by the intensity is
found to be a double-sided stretched exponential to the 1/3 power centered at
zero. The correlation between dwell time and intensity provides a dynamical
test of photon localization.
