Hello, Will. Geoff Taylor just sent me a report of a bug in the reference implementation of SRFI 19. (See below.) Would you mind taking a look? I'd be happy to publish a fix.

P.S. You know there's a bug in the (copy-time) implementation in the reference implementation, yes? The nanoseconds and seconds parameters are the wrong way round.
