I have a whole protocol for this.
You got a 5-count once there’s no one in front of you to go. Then you get a quick tap.
Then you get a 2-count to start moving. Then you get a double tap.
Then you get another 2-count. If you haven’t started moving by now, you get 1 tap every second until you fucking move for the love of fuck just fucking GO jesus tap-dancing christ in a Bethlaham drag show GO!!
A lot of science fiction writers try to address the problem of time when humanity becomes a space-faring race. Star Trek has the idea of a “Stardate” and instructed the script writers to just fucking make it up,
Meanwhile, Asimov in the Robots / Foundation universe, everyone still uses the idea of a 365-day / 24-hour day “year”, even if no one remembers Earth (except a R. Daneel Olivaw and a few others).
And Kim Stanley Robinson in his Mars trilogy does what OP notes – Martian years are longer, and the societies diverge pretty rapidly, within a generation, for a whole host of reasons.
