  • wouldn’t changing it just end up performative

    Exactly. Sidereal time does get rid of time zones and leap years, but it’s still referenced to a single physical object and relies on a arbitrary choice of start point. So it doesn’t create some perfect cosmic time standard.

    The international date line doesn’t help since that’s just 180° offset from Greenwich itself.

    The point of standards is that they can be followed by everyone. The AD/BC epoch is fine. The Greenwich meridian is fine. UTC is fine. Changing them would cause so much disruption that it cannot be worth it.

    Daylight savings can go die in a ditch though.


  • doesn’t change

    Citation needed.

    Do you use leap seconds to stay in sync with earth’s rotation? When would they be applied? How would spacefarers be notified of these updates?

    Also, what meridian do you choose for this ‘universal’ time? Is it still Greenwich? Because that’s peak colonial baggage.
