We consider the time dependence of the decays of tagged D0 and D0 into CP-conjugate final states f and f, or into a CP eigenstate F. We expand each decay width as exp (- Γt) times a series in Γt, where Γ is the average decay width of the mass eigenstates DH and DL, and examine the first three terms of the series. We show that experimental information on the coefficients of these terms allows in principle to compute all the relevant mixing parameters. In particular, depending on CP violation or conservation, we discuss the different possibilities to extract Δm and ΔΓ, i.e., the mass and decay-width differences of the mass eigenstates. We also comment on consistency conditions among the coefficients of the various decay-width expansions.
