  We re-examine and correct an earlier derivation of the distribution of the
Wigner phase delay time for wave reflection from a long one-dimensional
disordered conductor treated in the continuum limit. We then numerically
compare the distributions of the Wigner phase delay time and the dwell time,
the latter being obtained by the use of an infinitesimal imaginary potential as
a clock, and investigate the effects of strong disorder and a periodic
(discrete) lattice background. We find that the two distributions coincide even
for strong disorder, but only for energies well away from the band-edges.
