Re: Metric Time
#262Another excuse to share the wonderful Unix epoch clock: https://retr0.id/stuff/2038/ Watch face has 4 hands, one for each pair of characters in the hex representation of the current unix time. Being hex, it kinda makes it easier to understand for me in that the "minute" is 255 seconds. The next chunk of time is 65,025 seconds or about 18 hours. Then comes 16,581,375 seconds, which is almost 192 days.

We need tau-rational-time! We sleep for τ/3, noon is at π.
An hour is just an another name for a deciturn, or a deciday. Tau is not a good unit for angles in general, unless you have circles, or you need lengths of circumferences somewhere. (You want to paint your clock and calculate the amount of paint, or something.) Turn is the natural angle unit. And since the earth rotates 1 turn/day, the amount of turns is the same as the amount of days.

In the full version there is an unrolled map of the world down the side with the terminator drawn on which solves all those concerns. Even if those problems were harder to solve its far more valuable to have a single time for your meeting than multiple times (depending on the time zones and savings time of the participants). The pain of organising international meetings was one of the reasons I did this.
UTC?

Thanks, I've learnt something today. Just out of curiosity: is it just a joke, or is there an idiocy behind, such as Sovereign Citizen or similar?
Re: Metric Time
#267Considering it would take 3-4 generations to adopt a new time standard, I'd opt for some kind of "universal time" instead - not tied to one random planet (Earth) rotation speed. Think stardates, but real :)

Yes, a very confusing error. The metric time is the SI time (24h 60m 60s). The decimal time is base 10. French tried to get it used during the revolution and it did not work. Its the only unit that resisted decimalization, with a couple others ones in a handful of countries still using something called « imperial units ». Another similar thought experiment is binary clocks which I remember using to get use to read in…
>with a couple others ones in a handful of countries still using something called « imperial units ». The only country I know of offhand that uses "imperial units" is the UK. There's a different, but similar (and sometimes overlapping) system called "US Customary Units" that's used in the US. Imperial pints and gallons are NOT the same as US pints and gallons.

Why would sleeping time be a fraction of 2pi? > I'd guess that you're using rational numbers in the actual calculation anyways. Well, actually one uses floating point arithmetic, which isn't rational numbers either (as shown by the classic example a = 1/3, b = 3*a, then b != a)
I mean, we could be measuring time in radians. We already subdivide degrees into minutes and seconds, might as well call the day 2 pi radians. We sleep for 2/3 pi radians of the day in that case.
