Time-dependent CP violating phenomena probe the time evolution and the decay of beauty hadrons and allow access to the underlying dynamics.
In this talk, we present various time-dependent CP violation measurements in the $B_d$ and $B_s$ meson systems
that are performed using $pp$ collisions by LHCb and using $e^{+}e^{-}$ collisions by the B factory experiments BaBar and Belle.
For LHCb, we report measurements of the quantum-loop mediated $B_{s}^{0} \to \left( K^{-} \pi^{+} \right) \left( K^{+} \pi^{-} \right)$
and $B_{s}^{0} \to \phi \phi$ decays, and measurements of $B^{0} \to D^{\mp} \pi^{\pm}$ and $B_{(s)}^{0} \to h^{+} h^{-}$ decays.
For Belle, we report new results for the charm-less $B^{0} \to \pi^{0} \pi^{0} K^{0}_{S}$ and $B^{0} \to K^{0}_{S} \eta \gamma$ decays.
In addition, we present a measurement of $\cos 2\beta$ obtained by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*) h^{0}}$ with $D \to K^{0}_{S} \pi^{+} \pi^{-}$ that combines the final BaBar and Belle data sets.
