000003159 520__ $$aMeasurements of decay-time dependent CP violation are chief goals of the Belle II physics program. Comparison between penguin-dominated b→qq ̅s and tree-dominated b→cc ̅s results allows for stringent tests of CKM unitarity that are sensitive to non-SM physics.  This talk present first Belle II results on the mixing rate and lifetime of B^0 mesons, an essential validation of time-dependent measurements that requires detailed control of complex high-level capabilities such as flavor tagging and decay-time resolution modeling. Recent results on B^0→K_S^0 π^0 γ and B^0→K_S^0 K_S^0 K_S^0 are also reported.
