Basically that technology might allow us to extrapolate way more information than we are able to today. Maybe ALL information? Based on where every atom (in a limited space) is placed we might be able to guess where they were a picosecond ago, what about a second ago? What about a year ago?
The Total Perspective Vortex sort of work by that mechanic.

Update function would need to be reversible for that to always work (you shouldn't be able to get the same state starting from different states). And I think it's not the case, at least localy (heat one corner of a metal plate slightly, wait till it equalizes, guess which one it was).

Who would look out for the poor historians? It would make for a sweet game show actually, have a panel of historians make their best predictions on what really happened at an event, then "roll the footage!"
