    THIS MONTH I will be 1 Saturnian year old!

    That's Earth months, of course... I suppose Saturnian months would be based on a mean average of the orbital periods of Titan, Dione and Tethys (the largest 3 moons).

    Let's be even more exotic: how would you measure time in the changeless celestial environment of a DYSON SPHERE??

    Hmm... Sunspot cycles?
    If there was something orbitting the star inside the sphere, that would do the trick.

    Otherwise, any arbitrary scale would do. If a dyson sphere were built around Sol, I imagine the old seconds, days, and years would hang over as an obstinate meme.

    An artificial construct that completely surrounds a star, from the realms of wild speculation and science fiction.

    I guess that, if a Solar Dyson sphere is someday built, it would need a radius considerably greater than 1 AU to provide a comfortable climate - since the Sun would ALWAYS be vertically overhead, after all. Therefore Earth itself could be left intact in its original orbit, as a park or museum; terrestrial days and years would still be meaningful.
