Observing and clocking non-equilibrium electronic dynamics in real time has developed into one of the key areas of attosecond physics. Attosecond chronoscopy, originally developed for atomic systems, holds the promise to provide novel information on many-electron systems complementary to conventional spectroscopy. Its extension to condensed matter opens up new opportunities to explore electronic band structures and topology, electron transport, and decoherence. We will illustrate the timing of electronic processes in solids with the help of a few prototypical examples. They include the Eisenbud-Wigner-Smith (EWS) and transport time delay in layered materials [1, 2], the influence of the collective screening response on electron timing, the quest for identifying the speed limit of optoelectronics [3], and time-resolved valleytronics in graphene.
