Contextuality plays a central role in many key proofs for the impossibility of hidden variables in quantum mechanics. The most famous among these is the Kochen-Specker theorem, which originally applied to a Hilbert space of three dimensions, but much simpler proofs in higher dimensions have since been found. In recent years there has been a resurgence of interest in contextuality, and a number of experiments have been performed to test it in the four-dimensional context. Recently, it has been shown that contextuality may be interpreted as the result of simple measurement disturbance if the set of measurements chosen are time-like separated [B. La Cour, Phys. Rev. A, 79, 012102 (2009)]. In this work, several such experiments will be reviewed, and it will be shown that none are capable of ruling out a realistic, local hidden variable interpretation.
