  We develop a holographic framework for describing the experience of bulk
observers in AdS/CFT, that allows us to compute the proper time and energy
distribution measured along any bulk worldline. Our method is formulated
directly in the CFT language and is universal: It does not require knowledge of
the bulk geometry as an input. When used to propagate operators along the
worldline of an observer falling into an eternal black hole, our proposal
resolves a conceptual puzzle raised by Marolf and Wall. Notably, the
prescription does not rely on an external dynamical Hamiltonian or the AdS
boundary conditions and is, therefore, outlining a general framework for the
emergence of time.
