@ChrisBarker-NOAA, you didn't ask me, but I applaud your summary! Thanks. I don't think we should do (c). As I've said, we've discussed it many times before. Obviously it does have advantages, but there's a big disadvantage of complexity of software and convention in introducing another way, however marvellous it may be, to do something we can already do adequately. But I think it should be the subject of another issue.
I agree that (b) is not perfect, but it's in use, and that's not surprising because it's easy. You may not even need a library to compute timedeltas in this system, because the formula is fairly simple. It appears that I differ from Jim in thinking that (1) and (2b) should both be called `gregorian`. I think that's good because it's no change from the present convention for models and not much change for obs, and because they are interpreted and encoded in the same way. -- You are receiving this because you commented.
