We briefly review recent advances in measurement with ∼100 attosecond temporal resolution using the sub‐cycle electron dynamics inherent to high order harmonic generation. In particular a technique for utilising the electron wave packet chirp is illustrated by the measurement of ultrafast proton dynamics in the H2 molecule.
