Abstract Results of Monte Carlo simulations of the Comptonization of photons in a finite spherical Comptonizing cloud are presented. The energy dependence of the arrival times of the Comptonized photons is very different for different input photon spectra. If the delays observed in the high-frequency QPO of Cyg X-2 and GX5-1 are the result of Comptonization, multichannel time-delay measurements may constrain the energy of the input photons and thus provide important information on the accretion process in low-mass X-ray binaries.
