Rethinking multi-grain timestamps

I'm thinking humans here. And stock markets. Where $billions could hang on the precise ordering of events. :-)

And yes, I know that in our macro world all reference frames are - to all intents and purposes - the same. But as soon as you say "pick your favourite frame", you're going to get people fighting for the one that is to their personal advantage.

Which is my point. As clocks get faster (the point of this article) and distances get greater (we're talking about a network), the greater the importance of the chosen reference frame, which is a matter of politics not maths. Which means we cannot appeal to logic for a solution.

Cheers,
Wol
