As per Wikipedia:
The main advantage of a decimal time system is that, since the base used to divide the time is the same as the one used to represent it, the whole time representation can be handled as a single string. Therefore, it becomes simpler to interpret a timestamp and to perform conversions. For instance, 1:23:45 is 1 decimal hour and 23 decimal minutes and 45 decimal seconds, or 1.2345 decimal hours, or 123.45 decimal minutes or 12345 decimal seconds; 3 hours is 300 minutes or 30,000 seconds. This property also makes it straightforward to represent a timestamp as a fractional day, so that 2021-04-06.54321 can be interpreted as five decimal hours and 43 decimal minutes and 21 decimal seconds after the start of that day, or a fraction of 0.54321 (54.321%) through that day (which is shortly after traditional 13:00). It also adjusts well to digital time representation using epochs, in that the internal time representation can be used directly both for computation and for user-facing display.

So, how do we digitize military time:
"Mickey's big hand is between the 10 and 11 and his little hand is on the 6?"
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

Easy. Like everything else in the army, do it by threes.

I wasn't aware of these proposals. Decimal time makes sense. Decimal calendar, no. But...inertia.

The major problem with all of our natural timekeeping systems is that the "constants" on which they rely (day, year) are neither integral multiples of each other nor truly constant. This is why the time base for highly-accurate time measurements is TAI (International Atomic Time), determined by a set of ~400 atomic clocks worldwide. This is basically a count of seconds from an agreed base, and could in principle be converted to any other representation.
For atavistic reasons, humans like to have calendars and clocks that match the astronomical phenomena. In the northern hemisphere, we expect spring to start in March/April, autumn in September/October, etc. We also expect the year to have a whole number of days*. We therefore have such strictly-unnecessary phenomena as "leap seconds" and "leap years" to keep everything aligned, giving us UT1.
Given the above constraints, it would be impossible to design any calendar that did not make allowances for irregularities in the count. As such, we may as well remain with what most people feel comfortable.
* Months are artificial constructs in the civil calendar, so I'm not mentioning them

What do we do for those with a different number of fingers?
If a conversion is necessary, so long as we use binary for computers then we ought use a binary-compatible time: octyl or hex .
I mean, really, base ten is a commonly used custom but is really pretty stupid as choices go.

Yes, meaning it'd be slower than the current float that's used when trying to mutate.
Also, if we are changing anyway, why not pick something like Swatch Internet Time - Wikipedia[^]?
I'd already be happy if they stopped with summer&winter time

The 'nice' thing about the current system is that 24 and 60 are divisible by a lot of numbers making it easier to calculate fractions of days, hours and minutes. I don't know how Siri would respond to setting a timer for 33.333333... minutes.

Also, you can make the major divisions on a circular clock face with a compass.

Oh hell no! How would you ever differentiate between those times when you were specifying a real 'half' of an hour versus fifty minutes??? .25, .5, and .75 are commonly used now for specifying hours. It is a recipe for confusion, unless you change the entire world. The almost non-use of the metric system in the US is proof that isn't going to happen.

x:30 versus x.5? 
But I agree with you, that's why I have always rounded to quarter or hour when writing down times in a project, some days it goes up, some days it goes down, but working with 1/4 units is way easier to compute and to compare for a human than many other alternatives.

There's the Julian Date (day fractions). Used in Astrometry.
Julian Date "zero" is 1 January 4713 B.C. 12:00 UTC.
April 6, 2021 6:54:00 UTC is JD 2459310.78750

So, it is settled, I will change positions internally in my company, and be closer again to software development. Embedded world in automotive is just moving (ha!) a lot at the moment with electrification of vehicles, autonomous driving, AI, connectivity, ..., plenty of interesting topics, so I am a bit excited to join development again. My company is big enough that this change is like changing companies - new workplace, new colleagues, new products, a complete different environment.
I have been that "clueless" technical manager in the last decade you guys bitch about in some lounge posts from time to time - I chose to step back from this career, which likely means a dead stop in any kind of career in my company, because you cannot recover from this - but then, what is exactly career ? As a tech and teamwork lover, the management spheres were too far away from reality, and too dehumanizing. In the past, I really believed that success could be achieved without 20% profit increase targets each year, without using people as the first resource to delocalize or get rid of when things do not run as expected, without talking "empathy, entrepreneurship, .." and not believing a single word of it... I was sadly wrong : in the end, money talks, always. If I cannot change the world, let's change at least mine
