We calculate the elliptic flow of thermal photons from Au+Au collisions at RHIC energies for a range of values for the formation time {tau}{sub 0} but a fixed entropy (or particle rapidity density). The results are found to be quite sensitive to {tau}{sub 0}. The value of v{sub 2} for photons decreases as {tau}{sub 0} decreases and admits a larger contribution from the quark gluon plasma phase, which has a smaller v{sub 2}. The elliptic flow coefficient for hadrons, however, is only marginally dependent on {tau}{sub 0}.
