  In the AdS$_3$/CFT$_2$ correspondence, physical interest attaches to
understanding Virasoro conformal blocks at large central charge and in a
kinematical regime of large Lorentzian time separation, $t\sim c$. However,
almost no analytical information about this regime is presently available. By
employing the Wilson line representation we derive new results on conformal
blocks at late times, effectively resumming all dependence on $t/c$. This is
achieved in the context of "light-light" blocks, as opposed to the richer, but
much less tractable, "heavy-light" blocks. The results exhibit an initial
decay, followed by erratic behavior and recurrences. We also connect this
result to gravitational contributions to anomalous dimensions of double trace
operators by using the Lorentzian inversion formula to extract the latter.
Inverting the stress tensor block provides a pedagogical example of inversion
formula machinery.
