We review the experimental methods to measure mixing and time-dependent CP violation in D⁰ decays into two hadrons. While these phenomena are usually neglected for D⁰ →K^- π^+ decays, this approximation is not always justified. In particular, it produces a bias on the measurement of the parameter y_(CP), when this is performed by relying on D⁰ →K^- π^+ decays as a normalisation channel, whose size is around 40% of the precision of the current world average. Finally, we estimate the sensitivity to the weak mixing phases achievable by studying D⁰ →K^- π^+ and untagged D →K^- π^+ decays, where D stands for either of the D⁰ and D̅⁰ mesons. Contrary to Cabibbo-suppressed D⁰ →h^+ h^- decays, these decay channels allow to measure these phases without final-state dependent nuisance contributions from the decay amplitudes, but their sensitivity is lower by a factor of six.
