Earth's changing spin is threatening to toy with our sense of time, clocks and computerized society in an unprecedented way — but only for a second.
For the first time in history, world timekeepers may have to consider subtracting a second from our clocks in a few years because the planet is rotating a tad faster than it used to. Clocks may have to skip a second — called a "negative leap second" — around 2029, a study in the journal Nature said Wednesday.

It’s been proven that clocks actually run a little faster on satellites orbiting Earth. It has to do with gravity being stronger at the Earth’s surface.
So if we can get everyone in the world to walk in one direction, it will affect the Earth’s spin in the opposite direction.
For how long must we walk? I can’t say, as I cannot find my slide rule. So I’m unable to make any calculations.
As a side note, I guess anyone under 55 has no idea what a slide rule is.
LOL
OK take your pick... and always be correct..
VMelting polar ice is slowing the Earth’s rotation, with possible consequences for timekeeping

Global warming has slightly slowed the Earth’s rotation — and it could affect how we measure time.
A study published Wednesday found that the melting of polar ice — an accelerating trend driven primarily by human-caused climate change — has caused the Earth to spin less quickly than it would otherwise.

[Stop five people on the street and ask them what time it is on their watches. You’ll get five different answers.]
Does Anybody Really Know What Time It Is? Does anybody really care?
Oh dang. You beat me to it.
Good work.
That’s beacuse time is relative............

See my post #41.
Funny thing is, the older I get, time seems to go by faster….🤔
"Kromega III. It’s like asking a stranger for the time."
I thought it was the opposite. Clocks on the ISS run slower compared to Earth clocks because of their higher relative speed causing Einsteinian Time Dilatation.
https://planetary-science.org/astrophysics/time-dilation/
Clocks on the International Space Station (ISS), for example, run marginally more slowly than reference clocks back on Earth. This explains why astronauts on the ISS age more slowly, being 0.007 seconds behind for every six months. This is known as time dilation, and it has been frequently confirmed and validated by slight differences between atomic clocks in space and those on Earth, even though all were functioning flawlessly. The laws of nature are such that time itself will bend because of differences in either gravity or velocity, each of which affects time in distinctive ways. This phenomenon will have significant implications for interstellar or intergalactic travel.
The earth has been slowing down since the formation of the moon. When the moon formed the rotation of the earth was much faster, about 10 hours. The orbit of the moon was much smaller and faster. Over time there has been a gradual tidal transfer of earth’s rotational angular momentum to the moon’s orbital angular momentum. The moons orbital period is longer than it had been, but the radius is greater.
Circular orbits net energy and angular momentum increase with increasing radius. The moon’s orbit is not circular, but the same principal applies. The total kinetic energy stored in the earth’s rotation and moon’s orbit is decreasing, but angular momentum is conserved. The lost kinetic energy is dissipated by tidal friction.
ABC is the lukewarm water.

Does that mean we’re aging faster.
BTW, the moon is moving farther away from earth as we speak. and the sun is expanding and will die off in about 4 1/2 billion years, but, we all will have been toast 2 billion years before that. We must do something about it, and find a new star and planetary system to move to.
But, we must act soon, before it’s too late.
Global
Warming slows the earth!!
Then like an hour later
The earth is spinning faster and we need to adjust the clocks!!
What a bunch of nonsense. Talk
About conflicting science!!
And you run, and you run to catch up with the sun
But it’s sinking
Racing around to come up behind you again
The sun is the same in a relative way
But you’re older
Shorter of breath, and one day closer to death
Does anybody really care?
You’re probably right: I’m going by memory, and it ain’t what it used to be..
a big nothing...compared to changing your clock twice a year..
And if we could only find a way to enhance this process, we could all live forever.
