So by putting the offset and the extension to say "adjust the offset to the current timezone", you get a treatment of floating which is basically "local time but we don't know the location/timezone yet".

It strikes me then that the fundamental problem here is that the goal is really to create a standardised serialisation of some date formats **that are not datestamps**, that are commonly used across applications on the web. It should use the same elements of syntax as RFC3339 but it's not exactly an "extension". All the problems seem to stem from trying to enforce that they can also be treated as single points in time.
