2038: only 21 years away

Can we stop treating time in a simplistic linear fashion, please? Given the general relativity theory, time should be expressed as a (potentially infinitely long) vector of "stretch" factors for different points in the timeline, and a hashmap of such vectors, to allow different points of view, as well as a scrambling function to represent the route of a Tardis as a complicated directed, cyclical graph of points of view of stretching vectors, combined with a seed value for scrambling to represent the Doctor who was using the Tardis at any given, if you pardon the expression, time.

And this is still a simplistic model, since it doesn't take into account retconning for narrative purposes at all. But adding the retcon compressor is left as an exercise for the reader.

After that, we can finally have some peace of mind as far as time representation goes, and tackle the three fundamnetal unsolved problems in computer science, namely cache validation, naming of things, and counting beyond two.
