Sorry that was supposed to be just to Richard Having gotten into the survey, I can say it's one of the better surveys I've seen, though it's a bit lacking in the 'how to implement it' side of things.
I plan on writing down the results of the debates we've had here and submitting that, in a form that's greatly reduced in volume and rancor... Over on the NTP list, it's become clear that there needs to be a universal format for distributing metadata about time scales so that all use cases can cope, not just the 'keep time in real time' case that's been a prior focus. To disseminate time scales, one must have additional information about them: where they deviate from some standard / benchmark and where they have disconformities (eg leap seconds) as well as for the span of time the information is valid over.
