  There are, inevitably, complications. In the broad run of cases the temporal relationships between and within our perceptual experiences may accurately reflect the temporal relationships between the events we perceive, but this is by no means always or necessarily the case. If I were to see a star explode whilst hearing a clap of thunder (a remote coincidence, admittedly, but by no means an impossible one), I would be mistaken to conclude that these two events were in fact simultaneous. Since the light from the star has taken years to reach me, whereas the sound from the thunder has been delayed by only a few seconds, my experience is presenting as simultaneous events that are non-simultaneous. There are further complications on the micro-temporal scale. It is possible for quite striking ordering discrepancies to arise on shorter time-scales – i.e., of few tenths of a second, with stimuli measured in a few tens of milliseconds. In the case of the ‘flash-lag illusion’, for example, stimuli which are in fact simultaneous appear as successive (for more on this see Section 3 of the supplementary documents  Husserl, the Brain and Cognitive Science  and the supplementary document  Interpreting Temporal Illusions).
