Holy fucking shit same

It contacts a time server, which tells it the time. The time server gets its time usually from a government official time. Otherwise, you tell it what time it is and it has a chip with a battery that keeps track of how much time has elapsed.

So what you're saying is even the fucking time is controlled by the cianigger botnet

it has clock

It has a real-time clock chip + synchronises regularly with a time server.

Time is a human construct to begin with.

>The time server gets its time usually from a government official time
More or less.
The 1st level of servers synchronizes with atomic clocks.
Your computer contact servers to get the time, those servers themselves contact other servers to get theirs.
As a normie, your computer never interacts with the first level.

The motherboard manufacturer sets the time before the MB rolls off the conveyor belt.

What if the battery died?

there is a tiny battery (kind it like the ones in Casio watches) that keeps track of the time when the mobo is off

to specify, the battery doesn't keep track of time (obviously) but the clock that it's powering does.

It has a real clock on the motherboard, which it ignores and gets time from server.

CMOS, just to clarify for OP

Then the computer forgets what time it is, and thinks its Jan 1 1990 or something of the sort when you turn it on. Older computers also forgot all their BIOS configuration stuff, I think newer machines have flash so that that doesn't happen.

It's pretty rare to see a dead CMOS battery these days, they usually last well over a decade.

botnet gives a time

it uses something called a quartz oscillometer to measure universal time waves. maybe you've heard of cosmic background radiation before. a fairly recent discovery in physics has been the existence of an omnipresent time wave background radiation. these time waves can be measured and transformed into the correct local time using quartz crystals. this is also the reason we have different time zones; times determined using oscillometer chips drift over distance.

some astrophysicsts that study this phenomenon have even theorized that this time wave radiation could make short-distance time travel feasible, though this is bottlenecked by how fast a vehicle humans are able to construct can move. spacecraft are the most promising, of course.

This is the first documented account of this method of timekeeping. Image is of Walter Belk (left) and James Anchov (right) circa 1932. The quartz crystals are visible on top of the radiography machine.

It's been theorized that the time keeping quartz crystals use a similar energy as that contained in JO crystals.

There's a clock on your motherboard.
Also your operating system synchornizes this clock with an online time server (en.wikipedia.org/wiki/Network_Time_Protocol). Of course it's never going to be 100% accurate because there's latency involved and you can't really find End-to-end delay unless both systems already have a synchronized clock.

linux will log "superblock last mount time is in the future" but carry on booting. windows doesn't even check for time travel afaik.
security certificates can expire by having the system date predate the issue date, that's always fun.

Explain how raspberry pi's keep time without having a battery, then.

they don't. they acquire the time via ntp on boot.

There's a hamster wheel inside that counts one second for every rotation

This thread made me think, could the georgian calendar be wrong? Like sometime in the previous two millennia, humanity collectively missed a day or got wrong in which date it is?

The Georgian calendar isn't even 2000 years old. We switched from the Julian calendar in 1582. The ruskies still use that one.

Also, there's no such thing as "wrong date", dates are an artificial construct to begin with.

First of all the computer is not yours.

>dates are an artificial construct to begin with.
yes I know that, what I mean is has there really been 2 days and 2019 years since we created whatever calender we are using

No, it's not. The calendar we created is less than 500 years old with an arbitrary starting point approximately 2019 years ago.

Does anyone know how Jow Forums can create Opensource time? Like when some one says 12 o'clock we tell them it is actually 32 sst. Sst would stand for Stallman standard time. We can then finally have gnu/time.

First of all, calendars never measured the time since when they first appeared. They always used another point of reference. For example, the years since Rome was built or since the birth of Jesus of Nazareth. You can probably see the problem with that though. We don't know when Jesus was born exactly and you could argue that Rome was already a thing before it was given a reference date. Our actual AD date using the Gregorian and Julian calendars might theoretically be between 2012 and 2014.

It asks another computer for the time

TURN IT OFF TURN IT OFF

The real question is how do you convert from computer time to microwave time?

retard

>how Jow Forums can create Opensource time
How can I fund this

It asks.

Time is an objective certainty we just translate it so it's legible to humans. The computer exists in the same realm as time and can easily interpret it for us. This action between the computer an time is called a "handshake". As computers get better, so do handshakes, which also become more and more convoluted, and precisely defined as advancements in technology are allowed to continue. At this point a handshake can exchange over 300 betabits of information in a single peteesecond.
