You laugh but its true. Long ago many disjointed parts of the planet didnt even know there were other places or countries or that the world was round or tat it rotated. So some godforsaken tribe in who knows where only had the ability to cound days and years because of seasons LOCALLY. So they knew perfectly well how old they were. They may have even known the time locally in some arbitrary way before clocks, hours, minutes etc. But they certainly couldnt know the time in some other yet to be descovered place. So the brits invented time, and time zones. And thats why I am at zero. And other places are zero plus or minus 1 hour around the world. The brits invented time...
And
. And the industrial revolution, steam, clocks, etc.
