We analyze recently measured [1] interference patterns in the momentum-resolved single-ionization photoelectron spectra from helium by comparing the interference of contributions to calculated photoelectron spectra that originate from a few selected sub-IR-cycle time intervals during the laser-atom interaction. For contributions from just two time intervals that are centered at successive maxima of the laser-electric field with lengths of a few attoseconds, our calculation reproduce the measured interference structure in the momentum-resolved spectra. \\[4pt] [1] R.
