  We provide a general analysis of time reversal violation arising from
misalignment between quark and squark mass eigenstates. In particular, we focus
on the possibility of large enhancement effects due to the top quark mass. For
semileptonic decays of the charged mesons, $K^+ \rightarrow \pi^0 \mu^+
\nu_{\mu}$, $D^+ \rightarrow \overline{K}^0 \mu^+ \nu_{\mu}$, and $B^+
\rightarrow \overline{D}^0 \tau^+ \nu_{\tau}$, the transverse polarization of
the lepton $P^{\bot}_l$ is a $T$-odd observable that is of great experimental
interest. It is noted that under favorable choice of parameters,
$P^{\bot}_{\mu}$ in $K^+_{\mu3}$ decay can be detectable at the ongoing KEK
experiment and it holds a promising prospect for discovery at the proposed BNL
experiment. Furthermore, $P^{\bot}_{\tau}$ in $B^{\pm}$ decay could well be
within the reach of $B$ factories, but $P^{\bot}_{\mu}$ in $D^{\pm}$ decay is
not large enough for detection at the proposed $\tau$-charm factory.
