"why is there an extra second? m x"
To keep civil time in line with the sun’s movements, we occasionally add a leap second to the time measured by atomic clocks. We do this roughly every two years. This gives us the time scale that is currently used for most everyday purposes around the world. It is often called ‘Coordinated Universal Time’, or UTC. |

Really accurate. That's all I know.
I've just looked up the definition:
an extremely accurate type of clock which is regulated by the vibrations of an atomic or molecular system such as caesium or ammonia.

More interestingly IAT is coordinated by several atomic clocks around the world!.. Why because time is not the same at any given point?
Your clock may say 00.59.59 because your in a ground floor flat... But mine at a slightly higher height on the third floor will read 1 already because thanks to Eisenstein we know time doesn't flow evenly.
Julia's Cesar couldn't grasp time and neither did pope Gregory?

"There is talk about scraping this, but experts say we could slip up to three minutes ahead of time by 2100, and about half an hour by 2700."
.
I think I read in popular mechanics last year that there was an American outfit with a clock accurate to 1 second per 5 billion years.... Or to put it another way, the entire lifetime of earth  |
