  Purely time dependent solutions in four-dimensional
Einstein-Cartan-Kalb-Ramond (ECKR) theory of gravity are shown not to be
possible leading to a trivial vanishing of all Kalb-Ramond fields. This result
seems to contradict previously results obtained by SenGupta et al. (Class. and
Quantum Gravity 19(2002)677) where de Sitter spacetime solution is found as an
example of opticaly active spacetime. It seems that only inhomogeneous KR
fields are possible in four-dimensional torsioned spacetimes.
