  We study orientation and two-center interference effects in attosecond
time-resolved photoionization of the H$_2$ molecule. Time resolution of XUV
ionization of H$_2$ is gained through the phase retrieval capability of
attosecond angular streaking demonstrated earlier by Kheifets {\em et al}
[arXiv:2202.06147 (2022)]. Once applied to H$_2$, this technique delivers an
anisotropic phase and time delay which both depend sensitively on the molecular
axis orientation. In addition, the photoelectron momentum distribution displays
a very clear two-center interference pattern. When the interference formula due
to Walter and Briggs [J. Phys. B {\bf 32} 2487 (1999)] is applied, an effective
photoelectron momentum appears to be greater than the asymptotic momentum at
the detector. This effect is explained by a molecular potential well
surrounding the photoemission center.
