A time-reversal-violating spin-correlation coefficient in the total cross section for polarized neutrons incident on a tensor rank-2 polarized target is calculated by assuming a time-reversal-noninvariant, parity-conserving fivefold'' interaction in the neutron-nucleus optical potential. Results are presented for the system [ital n]+[sup 165]Ho for neutron incident energies covering the range 1-20 MeV. From existing experimental bounds, a strength of 2[plus minus]10 keV is deduced for the real and imaginary parts of the fivefold term, which implies an upper bound of order 10[sup [minus]4] on the relative [ital T]-odd strength when compared to the central real optical potential.
