Abstract	In 2022 Belle II experiment performed several time-dependent measurements analysing 200M of the BB decays. In these measurements, the positions of the displaced B vertexes are measured which requires excellent vertex resolution as well as knowledge of the interaction region properties. Measurements include the determination of the B0 meson lifetime and B0-B0bar mixing frequency, determination of sin 2beta in the tree-level dominated B0 -> J/psi Ks decay channel and in the penguin B0->KsKsKs decay. In addition, the Kpi isospin rule was proved in the B0->Kspi0 decays.
