  We develop a novel technique for modeling of atomic and molecular ionization
in superposition of XUV and IR fields with characteristics typical for
attosecond streaking and RABBITT experiments. The method is based on solving
the time-dependent Schr\"odinger equation in the coordinate frame expanding
along with the photoelectron wave packet. The efficiency of the method is
demonstrated by calculating angular anisotropy of photoemission time delay of
the H$_2^+$ ion in a field configuration of recent RABBITT experiments.
