That is more fundamental than we realize, as there is literally no other value in time except the fact that it's the same everywhere. The entire concept is that it's something we can all agree on, but we've lived with it for so long that we don't really realize that.

This reminds me of the following:

Imagine you had some items, and you gave each item a unique name, and then used the unique name you gave to the last item to describe their amount.

That's what numbers are, a commonly agreed upon way to label items so the last label indicates how many you have.

When boiling eggs or making tea, the fact that time is the same everywhere is definitely not what makes it useful.

"Boil your tea for thirty of my minutes"

I'm not saying that having standardized time isn't important for its usefulness (although if I know that my tea tastes well after 30 of my minutes, that's already useful to me).

But you wrote "there is literally no other value in time except the fact that it's the same everywhere". This is wrong.
