The resonant substructure in D0→KS0π+π decays is described by a combination of ten quasi two-body intermediate states which include both CP-even and CP-odd eigenstates and one doubly Cabibbo suppressed channel. We present a formalism that connects the variation in D0 decay time over the Dalitz plot with the mixing parameters, x and y, that describe off-shell and on-shell D0-D̄0 mixing. We analyze the CLEO II.V data sample and find the parameters x and y are consistent with zero. We limit (-4.5<x<9.3)% and (-6.4<y<3.6)% at the 95% confidence level.
