Lol, this was EXACTLY my high school sr. year social studies project in 1980, with roughly the same effort (sadly, I didn't create a working clock). I won first place, with just this. The only difference is I named the metric units 'mints.'

I just realized that the standard time watch face feels like it will follow the sun rising from left to set on the right side. But since the sun is rising in the east, it should be horizontally reversed. Or you should always look to the south / to the sun. Or it feels right because of my western idea of writing from left to right?

A 24 hour clock with midnight at the bottom tracks the motion of the sun if you are in the Northern Hemisphere looking South. If you are in the Southern Hemisphere looking North you need a clock that goes anti-clockwise.

I love how the example is super confusing. You sleep 3.33… metric hours. You fall asleep 9:50 metric time. You'd think we can just interchange the . and : so you should wake up 12:83…, or 2:83… the next day. But no, it's apparently 2:75 metric time. Why? Also nice how they IMMEDIATELY ran into a continuing fraction 1/3, which is exactly the point of the 60-minute hour, 24-hour day, or 360-degree circle: lots of facto…

Its like we have built our entire lives around another time system! /s You get similar problems converting between Freedom degrees and Celsius. Its just what people have built an understanding of.

You meant "Fahrenheit" rather than "Freedom", didn't you?

Also, no mention of the need for only 10 big-ass time zones instead of 24 relatively narrow time zones. The continental US might have only 2 time zones instead of 4.

Personally, I prefer 100 metric hours in a day. Each centiday is about 15 minutes. Each milliday is about 90 seconds. And a microday is slightly shorter than a second. But, sadly, this revolution won't occur until after I'm elected God-Emperor of Mars, so it is all rather academic.

And you'll have to make all your intervals slightly longer, due to Mars' solar day being 24h39m35s by standard Earth time.

We need tau-rational-time! We sleep for τ/3, noon is at π.

Spreadsheets already use "τ time", in that a day is a single unit, which could easily be defined to be "τ".

But how would daylight savings work? Or perhaps more seriously, time zones...

Anyway given the U.S. is still hanging on to measurements like Fahrenheit and inches, we're not going to see more sensible ways to measure and indicate time until most of humanity is living on a different planet.

Why is having fewer time zones a good thing?

Wouldn't this actually be confusing, because things would have to be happening at different local times depending on where you are in the time zone?
