  Measuring unitarily-evolved quantum mechanical two-time correlations is
challenging in general. In a recent paper [P.~Uhrich {\em et al.}, Phys.\
Rev.~A {\bf 96}, 022127 (2017)], a considerable simplification of this task has
been pointed out to occur in spin-$1/2$ lattice models, bringing such
measurements into reach of state-of-the-art or near-future quantum simulators
of such models. Here we discuss the challenges of an experimental
implementation of measurement schemes of two-time correlations in quantum gas
microscopes or microtrap arrays. We propose a modified measurement protocol
that mitigates these challenges, and we rigorously estimate the accuracy of the
protocols by means of Lieb-Robinson bounds. On the basis of these bounds we
identify a parameter regime in which the proposed protocols allow for accurate
measurements of the desired two-time correlations.
