It’s technically even more complicated than just scaling the day/seconds by to match a Martian sol. There are relativistic corrections that add up over time (Earth clocks would observe Mars clocks ticking at a different and non-constant rate). Good thing this is real :)
- fsh 6y agoThis is already the case on earth. UTC is defined at sea level and clocks run faster at higher elevations due to the lower gravitational redshift. This effect is easily observable with atomic clocks and has to be taken into account in any accurate clock comparison.
- kadoban 6y agoThat is not taken into account in timezones though, because it would depend on where you live. For MTC it probably is accounted for to some extent.
- hedora 6y agoThis was a plot point in Cory Doctorow’s Martian Chronicles: https://escapepod.org/2019/10/03/escape-pod-700-martian-chronicles-part-1/ https://escapepod.org/2019/10/03/escape-pod-700-martian-chro...

- Zenst 6y agoThe design needed to accommodate leap seconds, https://en.wikipedia.org/wiki/DUT1 https://en.wikipedia.org/wiki/DUT1 due to planetary rotation adjustments, would be fun. So much of how we define time is rooted in the Suns movement. Then you start to get the new factor of planetary distance wobble adjustments. Which will be fun as you start to add https://en.wikipedia.org/wiki/Three-body_problem https://en.wikipedia.org/wiki/Three-body_problem into time models.
