  Neutrino oscillations with three lepton families are described with a unitary
mixing matrix U in analogy to the quark mixing matrix V(CKM). If U contains a
nontrivial phase, there will be CP- and T-violating asymmetries at distances
large compared to E/D**2, where D**2 is the largest difference of neutrino mass
squares. The paper presents explicit expressions for these distance-dependent
asymmetries.
