I applaud that decision. I just have one question: will the zero point be chosen according to TAI or UTC? I would assume that you would choose time 0.0 = Jan 1, 2000 at 00:00:00.0 TAI (December 31, 1999 at 23:59:29.0 UTC), making the whole thing free of any UTC interferences. But there is an argument for making the zero point a recognizable boundary in civil time. The Olson library does that (its zero point is 00:00:10.0 TAI on Jan 1, 1970), but that's only because it's designed to be a drop-in replacement for the standard POSIX library and the time_t values have to match. Since you're changing the epoch, there's no compatibility constraint here . . .
