🤔

There is a system that «decimalizes» angles but I don´t have an English name for it never made it into anyof my English language textbooks for higher education (clearly, students should be spared for such anti-imperial nonsense.)

However, my point is that in this system, the quarter of a circle is 100 degrees («nygrader» in Norwegian - «new degrees» directly translated) . It would be more consistent then, to have a clock that goes to 400!

How about more time trivia then. So what is the deal with 12 hour clocks if we have 24 hours in a day? Furthermore, why 24 hours? And if they are 24 hours in a day, why are there 60 minutes and 60 seconds? This seems illogical, right? Maybe we should decimalize it, like we did with the metric system!

Sent the first picture to one of my unicycle friends with the comment, "5:80 already, the day is flying by" and he replied with "True" and the second picture.

Today from the #TimeLibrary my article about a quirky #DecimalTime system from the mid-20th century United States.

But first, how did we wind up with 24 hours in a day anyway? Why are there 60 minutes in an hour? Wouldn't 100 make more sense? Maybe, find out more...

Picture of a wrist wearing a single handed decimal watch with a blue strap and white stitching.  The face of the watch is white and numbered 01, 02, 03, 04, 05, 06, 07, 08, 09 and 00 to represent decimal hours, each of which is 2 hours and 24 minutes in traditional time. 

The time on the watch is around 4.69 which is about 11.15.

After two weeks with lots of trains (and hence some precision for times being needed) it is nice to go back to the single handed #DecimalWatch

I'm told the time cannot be 7.86 but if that were true, how come both my watches state this.

Since my LED watch might have upset people (being slightly misaligned) I'll switch back to this.

Why again are we not using #decimaltime ?

@moira @jarek No, the seconds are shorter. 1 decimal second is 0.864 SI seconds. 😉

P.S. Yes today I am acting as "reply guy" but since I regularly wear a decimal watch, display decimal time on my Android phone and also have devices that show Swatch .beats, I'll admit I failed to contain myself. 🤪

Anyway here is one of my watches with a picture taken at exactly midnight.

And since .beats are a decimal system, if you remove the forced timezone that .beats use, you can just read those last four digits as as percentage of the day to two digits and that actually makes them relatively understandable to a low level of resolution for most people. I added this to my README.

#DecimalTime

Alternative options

If .beats are too wierd for you, just remove the TZ=UTC-1 part from the script and you can alternatively read the last four digits as the percentage of day complete to two decimal places, in your local timezone. 0% → 25% [06:00] is early morning, 25% → 45% [10:48] is late morning, anything roughly around 50% is lunch time, up until 75% [18:00] is afternoon and over 75% is into the evening and night.

In front a terminal prompt on Linux, macOS or other *nix? Want to know the current time in Swatch .beats?

$ echo -n @; TZ=UTC-1 date "+((%H*60+%M)*60+%S)/86.4" | bc

I already have my own short shell script for this but just stumbled over this post where the core logic was compacted down to one-liner, which is pretty sweet.

Their full version is fancier still using figlet and watch to monitor (check it out).
