  The interaction of strong laser fields with matter intrinsically provides
powerful tools to image transient dynamics with an extremely high
spatiotemporal resolution. Here, we study strong-field ionisation of
laser-aligned molecules and show a full real-time picture of the photoelectron
dynamics in the combined action of the laser field and the molecular
interaction. We demonstrate that the molecule has a dramatic impact on the
overall strong-field dynamics: it sets the clock for the emission of electrons
with a given rescattering kinetic energy. This result represents a benchmark
for the seminal statements of molecular-frame strong-field physics and has
strong impact on the interpretation of self-diffraction experiments.
Furthermore, the resulting encoding of the time-energy relation in
molecular-frame photoelectron momentum distributions shows the way of probing
the molecular potential in real-time and accessing a deeper understanding of
electron transport during strong-field interactions.
