Time-domain interferometry (TDI) based on nuclear resonant scattering of synchrotron radiation by Moessbauer nuclei is a promising technique to study slow dynamics at the interatomic length scale. In fact TDI, being able to access at angstroem and sub-angstroem level the atomic dynamics in the time range between 1 ns and 1 $\mu$s, has the potentiality to significantly contribute to the study the microscopic dynamics of glass formers in a dynamical range otherwise inaccessible. The theoretical background of TDI will be briefly discussed along with its possible experimental implementations. Recent results on glass formers will also be shown.
