We present a measurement of the time-dependent CP asymmetry for the neutral
B-meson decay into the CP = +1 final state Ks pi0 pi0, with Ks to pi+ pi-.
We use a sample of approximately 227 million B-meson pairs recorded at the
Upsilon(4S) resonance with the BABAR detector at the PEP-II
B-Factory at SLAC. From an unbinned maximum likelihood fit we extract the
mixing-induced CP-violation parameter S = 0.72 +/- 0.71 +/- 0.08 and the direct
CP-violation parameter C = 0.23 +/- 0.52 +/- 0.13, where the first
uncertainty is statistical and the second systematic.
