Abstract	Measurements 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 𝐵0 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 𝐵0→𝐾0𝑆𝜋0𝛾 and 𝐵0→𝐾0𝑆𝐾0𝑆𝐾0𝑆 are also reported.
