Shit programmers say…
The problems of time zones only affect a handful of people, the wast majority of people nearly never think about this.
Epoch or standard time would just rename time zones, beucause currently you say hour offset from London, with “no timezone” you would have to say something like, noon is at 05:00 utc/epoch at that city, so nothing really changed
Industries where it actually matters already use UTC for everything, e.g. international flights.
It would make more sense to switch to base 10 minutes and hours than to “solve” the time zones
What would be easier with our conversation? I guess we are at the other side of the globe. I wasn’t answering because I was sleeping, you won’t answer immediately because you are sleeping, what would help if our clocked showed the same? Both of us sleep because the sun is down, not because the clock says something.
With long range space travel we will have to deal with the relativity of time as well. Lets say we define an Epoch and both of us do something exactly a googol second later but we live on a different planet, it wouldn’t be at the same time because of relativity. If I would say lets do something when it is 12:00 in London, UK, Earth, than you can convert it to your relativity and time zone.
About the intetplanetary usage of the current system, it’s already in effect, LTC aka Coordinated Lunar Time is already under development since this April.

So the solution is to just convert between time zones, and resync them sometime because they can drift because of relativity.
I don’t know how a base 10 day would work, it just annoys me that its reform wasn’t successful with the metric system. But I don’t know how it will work when people will live on Mars. A day on Mars aka a Sol is 24 hours and 39 mins. Will they have “Mars hour” which equals 1 Earth hour and 1.6 Earth minutes? If not, they could simply use Earth hours, than it won’t be possible to create classic circular clocks.
