It wouldn't help you. Windmills still have to be maintained. And, you still need reserve power when the wind dies down. If the reserve comes from batteries, the batteries will need periodic replacement, which is expensive. And if the reserve comes from offsite -- forget about the windmill and just bury your power lines.

POSIX.1 defines seconds since the Epoch as a value to be interpreted as the number of seconds between a specified time and the Epoch, according to a formula for conversion from UTC equivalent to conversion on the naive basis that leap seconds are ignored and all years divisible by 4 are leap years.

I think that's the only way to do it. You need some formula to convert between epoch time and component time, and a static formula can't account for arbitrary leap seconds. For computing purposes, instead of thinking of a leap second as making the day one second longer, think of it as a one-time adjustment to your clock.

All these anti-piracy efforts are predicated on the notion that piracy is bad, and that copyright is the only way or the only fair way artists can make a living.

If there are other ways for artists to make a decent living in a world where everything is copied freely, then you're completely right.

Yeah, they could figure something out about the hard drive space. Just put a tiny tax on all drives if you want to, otherwise enforcement is a problem. But the real problem is copying. As I recall, the deal is that you can make a copy of something for your own use, but you can't distribute copies. In my opinion, P2P should count as distributing copies, because the effect is the same. But yes, I know there's a counter-argument.
