A recent artlcle in Aug 25 Neuron Journal, claims that Boston University has discovered Time-Cells, that allow the hippocampus to map episodal memory, sequences according to temporal pseudo-sequences. These time mapping cells, map a sequence according to a bridging effect, that links events that happen at about the same time. There is evidence that there is some resequencing going on during the mapping. An earlier discovery was that the time information is probably linked to the event through wave-compression that allows the brain to speed up the event sequence, while passing it through the hippocampus. Other research in Sleep has indicated that slow wave sleep tends to trigger pseudo-sequences similar to those encountered during a real event, suggesting that the hippocampus can be used to remap events multiple times, which might aid in building a Meta-Index by which to categorize them.

In any case, this seems to indicate that the sequentiality of events, we experience, is indeed built from processes in the brain, and may not directly indicate the real order of activities, but bias them in favor of forming pseudo-sequences that "Make Sense" of our experience by adding cause-effect groupings in the Cause before Effect reorganization.
