The only time I could ever see us adopting new calendar systems is when (if) we eventually migrate off-planet into space colonies or onto other bodies in the solar system. Why? Because only then will each colony have a completely different notion of what a solar year is, and different (or even entirely artificial) notions of solar days. In these colonies a standardized calendar system may arise. Or a chaotic web of independent calendar systems.

Perhaps just a count of seconds from some zero point. Mark intervals in kilosecs and megasecs. Then the computer time-counter register will be the only clock anybody needs. Never mind 'Wednesday'. "See you in a megasec!" which is about 11.6 of our 'days'.

The problem there is that seconds are relative to movement. If you are traveling faster than earth, your clock is going to lose sync.

That is a problem that cannot be solved!
