  We define the $p$-adic trace of certain rank-one local systems on the
multiplicative group over $p$-adic numbers, using Sekiguchi and Suwa's
unification of Kummer and Artin-Schrier-Witt theories. Our main observation is
that, for every non-negative integer $n$, the $p$-adic trace defines an
isomorphism of abelian groups between local systems whose order divides
$(p-1)p^n$ and $\ell$-adic characters of the multiplicative group of $p$-adic
integers of depth less than or equal to $n$.
