Dear Jim Fine, let's support GPS and TAI but not LORAN-C for the moment.
What I propose is that data written with the next version of CF (in which we have made the calendar changes) will have no ambiguity. Metrical UTC time will be written with a new calendar e.g. `gregorian_utc`. UTC time which is written without leap seconds (and therefore non-metrical for some intervals) is `gregorian`. So you *will* always know how to decode the time coordinates correctly, won't you? I fear that there must be something in what you write which I haven't interpreted properly. Yes, the model `gregorian` calendar has days which are always 86400 seconds. The days are always the same length, but the length of the second does not vary. This is not the real world!
