A nearly bi-maximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T violation can be as large as one percent, leading to significant probability asymmetries between ν_μ\to ν_e and \barν_μ\to \barν_e (or ν_e \to ν_μ) transitions in the long-baseline neutrino experiments. The possible matter effects on CP- and T-violating asymmetries are also taken into account.LaTex 13 pages (2 figures included), talk given (by H.F.) at the Cracow Epiphany Conference on Neutrinos in Physics and Astrophysics, 6 - 9 January 2000, Cracow, PolandHigh Energy Physics - Phenomenologytext
