4:56, hey Sam, as an expert in the field of looking at clocks, I would like to point out that non atomic clocks also use atoms. In fact, you would be surprised to hear that most human made devices utilize atoms in one way or another.
Ok I'll go now
The best kind of correct
Interestingly enough even the humans building the devices consist of atoms. Almost everything in our surrounding is made of them.

Paused the vid just to find this comment xD
one thing that allways blows my mind is that its the same time in Tui ( western Gallicia) and Suwałki (eastern poland), meaning that if you cross the river to northern Portugal (0.2Km) and you have to change the hour in your clock, but you can go to the russian border of Kalinegrad (2 669,26 km) without needing to do so.
Country politics and Urban centers
It's the same in the states. There's a town near where I live that's right on a state border, and the suburbs across the border (in which many of the town's employees live) are an hour ahead of the town.
@@yousefnoori the two locations you mention aren't >2500km apart though.
What blows my mind is that there are half hour timezones in Newfoundland Canada and South Australia. It's 12 in New Brunswick but 1230 in Newfoundland. And it's 12 in Melbourne but 1030 in Adelaide.
@@Mike-rx5uu I could travel 2100 km and stay in the same timezone, or 50 km and be an hour ahead :)
"Because countries have guns and clocks don't"
That's a line I'm gonna remember for a long time lol
[citation needed]
Some clocks have guns.
You can set a clock to scare away pests from your field. Essentially, it's an alarm clock, except instead of ringing a bell, it fires a blank shotgun shell to scare away the critters.
Simon has clearly not been introduced to 'Murica properly.
I've never bought a clock that didn't come with a gun, nor a gun that didn't come with a clock...
"A language is a dialect with an army and a navy" is a good one, too.
Reminds me of an old Don Knotts & Tim Conway movie called “The Private Eyes”. I believe it was Conway’s character that invented a gun that went off every hour on the hour. Of course it ONLY fired on the hour.
Greenwich was chosen because at that time, the observatory (and related scientists, bureaucrats, etc) published the most accurate star charts for (mostly marine) navigation in the world. Funnily enough, I was watching a programme by a mathematician about this very subject yesterday.
IIRC it was the UK's railway companies which first brought about a standardized time for the country because, especially on single-track stretches of railway, having a train going, say, west to east and running on time based in Bristol, and another going east to west and running c.20 minutes ahead on London time, was asking for a train crash. And those things are bloody expensive (not mentioned as a reason for standardisation, but given when this was happening, probably a major factor).
What was the programme called?
Railway timetables were the problem. How do you correctly calculate when a train is going to depart or arrive, when every town is in its own time zone?
@@lawrencedoliveiro9104 With great difficulty!
But yeah, you'd have to calculate the time for every single stop using the intended time taken for the train to travel that distance, and either add or subtract the difference between the time zones based on which was ahead of the other. If time zones don't have rules that means it's very possible to "go back in time" given a large enough difference between two towns.
If you need to use multiple trains to get somewhere it can also be very annoying because you'll generally be unfamiliar with the time zone of the place you transfer, so you'd have to adjust your watch if you were lucky enough to have one, or work it out by hand. It's something most people would be able to handle with relative ease nowadays but back then people didn't quite have the same level of general education, and the need to keep precise track of time was new, so I'm sure it caused many problems.
With faster transit you'd also have to keep in mind the destination time if you were expected to be somewhere at a specific time, and work backwards from there to figure out when you had to leave. With each town in a different time zone, just knowing the travel time alone wouldn't tell you whether you'd be on time or not.
Honestly I'm not even sure all railway companies used the same method (maybe yes in the UK, but hard to know whether that was the case worldwide), in which case you'd have to compute things like local time, destination time, and/or point of departure time together.
I imagine it was a big annoyance for both railway operators and passengers alike, so it's no surprise that it was a major part of the push for standardised time zones.
Even now, though, time zones are still not quite as uniform as most people think. different DST dates, different DST offsets, non-integer time zones, multiple official time zones in one place, governments adjusting time on the fly, the fact that DST works the _other way around_ in the Southern hemisphere... It's such a huge pain to deal with. Luckily it's mostly programmers who deal with it nowadays. That way it can be easy for the general public. Though even that can be wrong (see governments adjusting time zones on the fly as mentioned above, occasionally not giving enough time for programmers to fix stuff before the change takes place).
It's better than it was, but it's still a huge mess. I'm quite thankful we can leverage computers to handle them for us nowadays.
that and the time ball in London harbour on the building just across the Thames. Said building is the old Royal Naval College, before the college itself was removed. The Admiralty charts from the Royal Navy are still to this day are considered the standard charts for marine navigation.
@Sean Embry Your sacrifice is appreciated!
Correction: hours have been in use since antiquity. The Ancient Greeks divided the time between sunrise and sunset into 12 hours, with night having three or four "watches." By the Hellenistic period, the night was divided into 12 hours as well. Al-Biruni was the first person to divide the hour into minutes and seconds (borrowed from the Babylonians) around the turn of the millenium.
I can't actually think of what might have happened to the hour in the 13th century that got you confused.
@@creepwood77 Also fun fact: 1/60th of a second is called a "third", for the same reason. There are also fourths, fifths, etc. Unfortunately thirds were never very popular, and the rest were never seriously used.
@@softy8088 It's actually called a "frame" and It's 0.016 seconds .
@@creepwood77 Yup, short for pars minuta secunda, which means second diminished part. The minute is from pars minuta prima. Though both phrases were orignially Ptolemy's names for the geometric minute and second, and were adopted for the temporal later. I assume al-Biruni used the modern Arabic words for second and minute which were obviously not derived from Latin, but I can't read Arabic and can't find that information with a cursory Google search, so I'm going to leave it alone and hope somebody who knows reads this
We have the babylonians to blame for the 60s in our time units. Should be nice decimals...
@@petertrudelljr get this base10 thinking outta my sight. Using 60 was our chance to correct the entire number system and abolish decimals. But noooo, we were already using it and its "simple". Cause who would want to be able to actually evenly devide things into groups other than 2 or 5, or to actually be able to easily do mental arithmetic. I'm still angry about this. base12 ftw
My favourite part of this whole story is the abbreviation UTC.
In English, it's called "coordinated universal time" - whose abbreviation is CUT.
In French, it's "temps universel coordonné" - AKA TUC.
So, in a compromise that means it makes sense to absolutely no one, we called it UTC!
I guess those dastardly French won in the end though - at least the "C" is in the right place.
Universal time coordinates is what I thought of 😅
The French went "We don't mind if it's not TUC, but we will absolutely not make the British right about anything.
Hats off to the lady who sold time!
You could say she was ahead of her time.
@@chad_b I mean, reputation is a thing. Why would you trust the time some random sold you is accurate when you could go to the lady that's sold a good chunk of the town that service?
Small overhead, 100% profit. Genius!
@@chad_b There's a difference between products and services. If the entire point of paying someone is to get an accurate time, you're going to go to the person you know gives accurate time, since if you just wanted a ballpark, it would not be at all difficult to just ask around and get it for free.
So time really is money?
I got to say the conference at 2:57 was pretty inclusive for a mid-19th century international event. Even Liberia got a seat.
Liberia was basically the US's little African brother for the latter half of the 1800s, and often went where they went. They're the sole reason the US went to the Berlin conference, too.
@@spikeESP thats not how words or concepts work,...
or more like the 'Merica wanted more votes so got its _allies_ to nod in its favour?
Countries that were convened were not out of inclusiveness, but rather as means of gathering votes and legitimacy for the GMT time, which was in a strong fight against Paris. This had to do with the influence that mapmaking and telecommunication industries have had until then, as adopting any one standard would mean business for one and bankruptcy for the other.
Most interesting attendee is the independent Kingdom of Hawaii.
Note: the railroads didn't institute time zones just because the inconsistent time was inconvenient, but because it was causing train collisions! It was very difficult to keep track of what train should be where at what time when the time was different at every location.
Having trains collide seems like it would naturally fall under the category of things that are inconvenient.
I like to imagine the UK got the UTC-0 timezone to spite the French who standardised the world with Metric.
That's not too far from the truth. The French _really_ wanted the prime meridian to go through Paris, but instead ended up going somewhere in between Angers and Tours. 😉
Actually, France and Spain changed from UTC-0 to UTC-1 because of WW2 ,France because of the occupation ,Pétain passed a law to change it to the one the German were using and Franco changed it to please Hitler .
Other country also have the wrong timezone (UTC-1 instead of UTC-0) because of that (Algeria ,Mali ,Niger for example) ,the Benelux should also be on UTC-0 ,instead of UTC-1 .
@@plumebrisee6206 it's UTC+1 in france and spain (CET, central european time), not UTC-1
Interestingly, some frenchman also pushed for clock time to be base 10 as the rest of the metric system, but people were like "clocks are already cumbersome enough, just don't do that"
But now the Brits change their time twice a year to spite all of Europe. But Europe experiences schafenfreude.
Remember that UTC was standardized in about the 1970s, while GPS didn’t come along until 1990 or so. So GPS was not a factor in the move from GMT to UTC.
What was more likely a bigger factor was WGS84. This was a standard reference for the shape of the Earth, which is not a perfect sphere. But the shape of the Earth affects the placement of latitude and longitude lines. As a result. 0° longitude no longer passed through the Greenwich Observatory, but went through a field a few hundred metres outside.
Another factor is the ambiguity in the definition of GMT. It might be the same as UT1, or it might be the same as UTC, it’s not quite clear. And the two are allowed to differ by up to 0.9 seconds. I suppose in a practical sense, whenever people say “GMT” nowadays, they really mean “UTC+0”.
This is probably the more correct reason for UTC, but GPS was around in the 1970's, development began in 1973 and the first satelite was launched in 1978. It was not considered fully operational until the early 90's when the last of 24 planned satelites became operational. Civilian use of GPS has existed since 1983.
A little fun fact about time keeping in Germany: the German Kingdoms, before they were united to the German Empire, had dozens of different time zone, each Kingdom had its own and they were each apart by like only a couple of minutes. Train companies had a problem with that since that made it difficult to establish a german-wide schedule, so they had their OWN time. All railway stations had 2 clocks, one showing the kingdom's time zone, and one showing the official train company's time zone, after which their schedule would operate. And as far as I know that lead to to the Kaiser establishing a nation wide time zone, when Germany united to the German Empire.
Having 2 clocks for "Railroad Time" and "Local Time" wad not unheard of in the States either.
@@Random3716 oh, interesting! I only heard of that case in Germany
Incredibly interesting! Thanks for sharing :)
@@_thereswaldothey had it in Britain aswell
It's a picture of Zurich although you mention Geneva. I hope to be featured in your yearly review
A bit of pedantry, my last in 2021. UTC and GMT are different beasts, quoting Wikipedia: English speakers often use GMT as a synonym for Coordinated Universal Time (UTC): in modern usage, this is incorrect - GMT is now a time zone, not a time standard.
You laugh at the idea of prime time, but bezos is actually building a giant clock in a mountain that will last 10,000 years. So him monetizing that doesn't really seem so farfetched.
Is it gonna vacuum up time from the universe then let us buy time to live with ?

The Netherlands should be in the same timezone as the UK, but it is in Germany's timezone due to some historical incidence which also caused the death of 6 millions jews. I don't know exactly what that was all about, but that's because all my educations come from that guy at HAI.
Even weirder: up until then, The Netherlands were on GMT+00:20, or 20 minutes ahead of the UK.
Spain is also on UTC+1, due to Franco wanting to align with guys who started that historical incidence you’re referring to.
Ireland was part of the United Kingdom for the period between the invention of GMT and the time we "adopted" on-the-hour GMT. We did not use that flag, and we were not a sovereign nation.
...and then about 10 years later we changed our constitution so we're technically on GMT+1 as "standard time" (which is observed during the summer) and then put the clock back an hour for winter time.
The fact that our time zone is effectively the same as the UK's but it's defined so differently really does amuse me.
Yes, you're the only country in the world that defined your basic time as summer time, and then vary it for the winter season :)
Also, Irish time before the shift to GMT was based on the meridian going through Dunsink Observatory. Now, why did Ireland use this rather than GMT? Because it's about ~30m different (which is quite a bit) and we're on an island with no rail links and thus no need to synchronise timetables with the then rest of the UK.
Geolawie yep. That's actually illegal in the U.S. States can and have (Arizona and Hawaii for two) ignore Daylight Savings, but no state can have permanent Daylight Savings without an authorization from Congress. I for one would love permanent DST here in Michigan. The sun sets at 5:00 here this time of year. In winter we would be the earliest time in the U.S. (4 hrs later than LA) and in summer we would be the same time as the rest of the East Coast.
Correction, latest time in the US
Atomic clocks measure the _length_ of a second. Observatories decide what the time is. The US Navy observatory seems to be the central source.

@good one do you sell sanitizer?
"Ye in "Ye Olde Coffee Shoppe" is just an older spelling of the definite article the. The y in this ye was never pronounced (y) but was rather the result of improvisation by early printers. In Old English and early Middle English, the sound (th) was represented by the letter thorn (þ). When printing presses were first set up in England in the 1470s, the type came from Continental Europe, where this letter was not in use. The letter y was used instead because in the handwriting of the day the loop of the letter thorn was often not connected to the upright, and so the thorn looked very similar to y."
I think more precisely "y" is used because the printing press was invented in Germany and mainly spread from there and "y" was just a rarely used letter in German which could therefore act as a substitute for thorn.
That's something of an oversimplification. Access to þ in early printing was not a problem since early print shops had tools to create new keys as needed from patterns (the development of alloys that were sturdy enough to by used for typing but soft enough to be reshaped as needed was one of Johannes Gutenberg's most important contributions to printing, incidentally). Rather, Þ/Ð hard largely fallen out of use with the literati of England especially in the south by the 14th century, replaced instead with variations of Y usually with other letters above it, and hence there was simply no demand for Þ or Ð by the time printing came around.

Hours were invented by Babylonians (Persians 🇮🇷 ) in the olden BC times, in fact the 24 hour subdivision if time is an invention of some Persian empire. What was invented around the 13th century were probably mechanical clocks, taking over from sundials and hourglasses.

Just earlier today I wondered why we decided to use middle of the night as the time a new day starts, instead of when an actual new "day" starts.
At sunrise.
So I created an excel document, copy pasted the sunrise, sunset and daylight time lengths,
Started to calculate how long a day would be because every day the time of sunrise only varied by few seconds, so only the time of sunset would change,
And everyday when you wake up at the same time, or go to work at the same time, you'll the have the same amount of sunlight outside...
Then I remembered not everyone lives in the tropics and it would be nightmare for people in Norway for example...
Why would it be an issue outside of the tropics? That minor difference is solely due to the equation of time, which is the same everywhere, right?
@@Anonymous-df8itNot the equation of time.
He based his start on sunrise and length of day on sunlight duration.
And let's say when is sunrise, and also how long a "day" (sunlight duration) lasts, is very different in non tropical countries, depending on their season.
@@RomanBelisarius A day wouldn't be the duration of sunlight. It would be the duration of sunlight plus the duration of darkness that follows it, and if one is long, then the other is short to compensate
@@Anonymous-df8it Sure, according to your convention of what a day is. But not OP's.

4:14 Clocks may not have guns, but they do rhyme with Glocks... so they'd win a rap battle.
It would be great if people/companies would use the correct UTC designation instead of the outdated GMT one. So many operating systems, apps, and websites still use the outdated GMT terminology instead of UTC. I personally think the initialism UTC looks a lot more modern than GMT.

The reason that midnight is when it is - because the deadliest day needs more deaths to count, especially the deaths from a certain falling glass ball
I think it's interesting that parts of eastern Oregon, and the western panhandle of Florida are just 1 hour apart.
The hour *as we know it today*-1/24 of a mean earth day-didn’t exist until when you said, but in its original sense-approximately 1/12 of the time from dawn to dusk-was part of the Greco-Roman standard for timekeeping, and as such WOULD have been recognized in the medieval period (though they’d be numbered differently with the first hour from what we’d call 6-7am and the twelfth hour from 5-6pm, and using a different system of 4 watches from dusk to dawn since sundials or literally looking for the sun’s position in the sky and estimating were the most precise and simplest ways, respectively to track it, neither of which worked at night). Solar hours, which are what modern clock hours were designed originally to roughly approximate, were the default when talking about time in most parts of Europe until trains and long distance sea navigation necessitated a shared mechanically precise clock. So a medieval peasant wouldn’t have understood the rest of the sentence and would be weirded out by anyone needing to track time more precisely THAN to the hour (all premodern societies understood “I’ll meet you at x time” as x +/- a couple hours, but that was a cultural difference necessitated by the imprescision with which time was kept not a lack of understanding of the consistent linear progression of time), they would’ve been familiar with hours, and depending on where, may even have timed their workday by them.
When I saw Australia in the list of not running in-line with time zones I got so confused and was like 'wait I've not been in sync by 10 or 11 hours my entire life?' then I remembered some states do daylight savings half an hour off set instead of an hour

Next you should do a video on daylight savings time, why it wastes more and it saves, and why keeping it around is the stupidest thing anyone ever thought of

Then again, there are many lacking in sanity these days (and for some reason they're usually the ones that are put in charge >.>)

Thank you for making the GMT line match up with the watchtime progress bar
I accidentally skipped ahead 10 seconds during the Brilliant ad and, “… I was notoriously bad at math and … quantum computing, machine learning, and logic,” became, “I was notoriously bad at magic.”
Since you mentioned GPS in 4:41, fun fact about GPS time: "GPS Time" is actually a related but different timing system from "UTC". The main difference is that GPS time uses an epoch in 1980, and doesn't use leap seconds, whereas UTC does. Spacecrafts in low earth orbits probably all use GPS time instead of UTC time for their calculations and time tracking, both because the lack of leap seconds makes them much easier to use, and because these spacecrafts all get their time from GPS anyway.
Other serious software with important timing applications probably use TAI, which is another related timing system to UTC. The primary difference between TAI and UTC is *also* that TAI doesn't use leap seconds, which allows you to accurately represent a moment in time with a number (in UTC, a number could represent two separate moments if it happens to be when the leap second occurs), and reduces issues with calculating elapsed time between two timestamps.
Seriously, leap seconds solves one issue but introduces so many more. If you use UTC in your code and don't know what leap seconds are, read up on them!

because I'm tired of world maps having a bit of Chukotka dangling up at the top left, I use the meridian through the centre of Erfurt, Germany as my prime meridian. Not only does its antimeridian bisect the strait between Diomede islands, thus fixing the Chukotka problem, it lets eastern countries be one hour ahead like they've always wanted to.
Questions I didn’t know I needed answer to once again.
Funny enough - for most every day devices and stuff atomic clocks on GPS sattelites are key to keep world in sync. Heck, if by any chance bunch of them would get damaged by some crazy solar storm coming from only true Corona, ton of things in world would stop working properly. So giving right road to nearest cliff might be smallest loss of it.
For observation purposes, getting "reference point" can be relatively easy as one can point aprrox. time of Sun being highest into sky. And that was base of most local clocks for ages and also need for "let's compare or watches.. time I mean - as long as my clock is exactly 2 min and 35 seconds behind my "co-worker" clock, we can keep working in sync without need to be in touch all the time.
There are, in fact, 25 times zones, not 24. Each time zone is, nominally, 15 degrees of longitude wide, except for the two on either side of the International Date Line, which are each 7.5 degrees wide. These two time zones have the same clock time but are one day apart.

2:52 there was an informal agreement that France would switch to use the Greenwich Meridian reference (instead of the Paris Meridian) and in exchange the UK would officially switch to the metric system. Both changes occurred in the same year 1884.
Also, the use of the Meridian of the Canaries dates back to the Middle Ages when the Canaries were the westernmost point in the known world, so all the longitudes would be positive values.
It's about time.
Or as Chicago sang “Does anybody really know what time it is?”
Basically the lady decides what time it is.

Happy New Year, Half As Interesting, thanks for the information shared on this platform, may you have a fruitful 2022.
1:08 Oh Yeah !!!

Cant wait to be in the "All the mistakes we made in 2022" video! Gotta get in there early!

"Erat autem fere hora sexta, et tenebrae factae sunt in universam terram usque ad horam nonam" ... was written down well before the 13th C.
He's both right and wrong. There wasn't a truly standard hour length back then, daylight time was divided into twelve parts(hours), whose length changed with the seasons. "Hora" does correspond roughly with an hour, but it could be much longer or shorter depending on the season.
Fact error:
There is only 1 time zone in China: GMT+8:00.
There is no "Xinjiang Time Zone" at all. Some local people choose to use local time, but the official time is still GMT+8:00.
