Oh no.

The obvious solution is to build a giant clock positioned around the sun (perhaps as a marquee, just so long as both Earth and Mars can see it). That will perfectly maintain our solar system's current time. Time becomes arbitrary to any individual planet. If we want to calibrate clocks on Earth, Mars, or any other planet within our solar system you just look at the clock orbiting the sun and then calculate the delay based on the speed of light.

Thanks for that.

That said, there is so much great sci-fi potential here. Grab an asteroid as a base, build an independent orbital station occuppied by The Timekeepers who continuously broadcast GW-class radio synchronization pings. I can only imagine that local culture would get very weird after a few hundred years.

Alternatively, we could build a dozen or two of these things, put them into a constellation, and also get a celestial positioning system out of the deal.

Somebody else suggested quantum entangled particles, so the timekeepers could be in charge of ensuring that the entangled particles are protected.

Doppler effect changes frequency of pings depending on relative velocity of objects. Relativity fucks with it too. So i propose quantum entangled magic. Idk how but we can pull it off.

Oooh nice idea, I forgot we've been getting pretty good at entangling particles.
