I think that the Post is a good start but the poster needs help defining practical examples of Time. Watches, and judgements of when to do things are not what Science regards as Time, Watches can be used as simply alarm clocks, which make no reference to any Social Network of Time; I could simply go about measuring how fast I run a mile with my watch rather than figuring out when the best time to start work, A more useful measure of Time is actually related to daylight and the sense of sight or the feeling of being awake.
In that sense a Unified approach to Time is necesary that we can have both a. a general sense how old/young we are and b. a world wide agreement on units of measure for age.
These two arguments seem like repeating the same thing twice but notice that in the future someone living on mars will have difference year length than someone on Earth, so if I were 1 year old on Mars I would be more than 1 year old in Earth years; therefore the Units of Measure must be the same, simply having many difference units of measure does not fulfill Unified Time for obvious reasons.
So in conclusion of this thorough but not extensively researched post; Unified Time requires a Universal Unit of Measure, this would change a few things in our vernacular: for example instead of simply saying I will see you tomorrow, You must say I will see you the next Earth Solar Cycle, but when referring to age or dates, you will use the Universal Unit of measure and leave out all Earthly considerations including the length of the Solar Day.
Am I talking in Science Fiction, probably, but it's supposed to be forward looking, I am not suggesting anyone lives on Mars yet, just that someday...we might have to plan ahead for it.
