The BaBar detector at the PEP-II asymmetric B Factory at SLAC collected a sample of 23M B-anti-B pairs in the years 1999 and 2000. Using this data sample, we measure the amplitude of the time-dependent CP-violating asymmetry in neutral B decays to the CP eigenstates B0 --> J/psi K0S, B0 --> psi(2S) K0S and B0 --> J/psi K0L. We find a value of sin2beta = 0.34 +/- 0.20 (stat) +/- 0.05 (syst). We also present preliminary measurements of the B^0-anti-B^0 oscillation frequency and of the lifetimes of charged and neutral B mesons.
