  The neutrinos from galactic supernovae can be detected by the Sudbury
Neutrino Observatory and the Super-Kamiokande. The effect of neutrino mass can
show up in the observed neutrino signal by (i) delay in the time of flight and
(ii) distortion of the neutrino energy spectrum due to flavor mixing. We
discuss a combination of the two effects for both charged and neutral current
processes in the detectors for realistic three flavor scenarios and show that
neutrino flavor mixing can lead to non-trivial changes in the event rate as a
function of time.
