Maybe what I meant with `nothing looks quite right': seconds as float, microseconds as float, nanosecond as 0..999, nanoseconds as 0..999999999 with mandatory keyword that precludes microseconds - all can be made to work, none seems completely satisfying.
In fact, I don't really have a use for it from python - but something would be needed in C for the implementation of datetime.from_timespec and time.from_timespec that calls the constructor
that's the datetime.time.from_timespec btw.
PyObjectCall_CallFunction(clas,"...",...) - can this happen and remain hidden from the python layer?

I wonder if the datetime module is really the right location, that has constructor(year, month, day, ..., second, microsecond) - with 0<ms<999999, no millis. adding 0<ns<999 would seem quite ugly, in fact nothing looks quite right.
We can make nanosecond a keyword-only argument, so that
time(1, 2, 3, nanosecond=123456789) -> 01:02:03.123456789
and
time(1, 2, 3, 4, nanosecond=123456789) -> error
Users will probably be encouraged to avoid positional form when specifying time to subsecond precision. I would say time(1, 2, 3, microsecond=4) is clearer than time(1, 2, 3, 4) anyways.
Another option is to allow float for the "second" argument:
time(1, 2, 3.123456789) -> 01:02:03.123456789
