  We give evidence based on level-truncation computations that the rolling
tachyon in cubic open string field theory (CSFT) has a well-defined but wildly
oscillatory time-dependent solution which goes as $e^t$ for $t \to -\infty$. We
show that a field redefinition taking the CSFT effective tachyon action to the
analogous boundary string field theory (BSFT) action takes the oscillatory CSFT
solution to the pure exponential solution $e^t$ of the BSFT action.
