Ellipticals, Bulges and Disks: what happened when?

I will use the colours and spectrophotometric indices for samples of local early-type galaxies to estimate their luminosity weighted ages and confront current hierarchical models of galaxy formation. Preliminary results from Abell 2218 (z = 0.17) will also be presented.
