The time-dependent Comptonized output of a cool soft X-ray source driftinginward through an inhomogeneous hot inner disk or corona is numericallysimulated. We propose that this scenario can explain from first principles theobserved trends in the hard time lags and power spectra of the rapid aperiodicvariability of the X-ray emission of Galactic black-hole candidates.Comment: 10 pages, including 2 figures; uses epsf.sty, rotate.sty; accepted for ApJ Letter
