We study networks obeying \emph{time-dependent} min-cost path metrics, and
present novel oracles for them which \emph{provably} achieve two unique
features: % (i) \emph{subquadratic} preprocessing time and space,
\emph{independent} of the metric's amount of disconcavity; % (ii)
\emph{sublinear} query time, in either the network size or the actual
Dijkstra-Rank of the query at hand
