Time can mean many things, but Hillis's machine
needs to track a particularly messy version: Earth - surface clock / calendar time, which is based on a byzantine
agglomeration of astronomical rotations, orbits, and perturbations of hugely varying lengths, overlaid with arbitrary cultural whims about how to divide it up.
That does not provide a complete solution and third party collaboration and aggregation channels are evolving, but I don't really see that they
need «their own media channel» — will it not be an
agglomeration of media channels?
