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 :)
It mentions the days being longer, but what about the years? What even constitutes a year on Mars? Seems like more thought needs to go into how this would work if/when we become interplanetary. Assuming knowing where you are in the year has any value on Mars, we'd want some way to track that. I wonder also how this would work on the moon.
My sleep schedule has a ~25 hour period, so I'd actually use this. :) Been doing it for 20+ years. Most of 2021 I've awakened around 07:00 MTC. It's 10:27 as I write this, so I've been awake for about 3 (Mars) hours. <a href="http://marsclock.com/" rel="nofollow">http://marsclock.com/</a>
We already had GMT which ended up being called UTC - "Universal". If we'd stuck with GMT or defined E(arth)TC or similar, then MTC would make sense.<p>I do like it though, good to see some innovation in the AFD jokes department.
