Does anyone see any reason to specify, as part of the SRFI, when 'time' starts? Marc Feely didn't like 1/1/1900 for a starting point (prefers 1/1/1970), for example. The starting point clearly effects the implementation, or vice versa, and I'd rather give this one to the implementers. I'm leaning towards just leaving this part all together for 'universal time' and 'Julian day number'. -- Will
