Coppertop claims her old watch is dying: it's running slow, losing time.
I know better.
In the far future, people will have wildly advanced technology. But time, as they say, will still be money. People will be willing to pay quite a bit for a well-placed extra few minutes here, or an hour there. But time, like the other spacial dimensions, can neither be created nor destroyed. So where do you get it?
Easy. Mine it. From the past. From around the twentieth and early twenty-first centuries, when people are so distracted by all the social changes that they'll barely notice it. They'll just chalk it up to being busy. Take just a few milliseconds out of every second, or even a good chunk of each second during peak demand periods. Squeeze it there in the past, stretch it out here in the future, and sell it at premium prices.
When you look up at the clock and wonder where your day went, well, now you know. Some future person with cash to burn is enjoying an extra few minutes lingering over drinks, or some desperate student who hasn't been born yet just scored another hour to cram (or fritter away trying to cram) before a final that hasn't yet been planned for a subject that doesn't yet exist.
Somehow, in all the mining, they missed Coppertop's watch. It's not losing time; it's keeping it just fine. It's the rest of us that are losing it.
