Actually, time.strptime() returns a struct_time object. Would it be possible to extend %S to parse floats then add a microseconds (or whatever) field to struct_time objects that is available by attribute only? In Py3k it could worm its way into the tuple representation somehow (either as a new field or by returning seconds as a float).
Right, it's a struct_time object; just force of habit to call it a time tuple.
And I technically don't see why a fractional second attribute could not be added that is not represented in the tuple. But I personally would like to see struct_tm eliminated in Py3k and replaced with datetime usage. My wish is to have the 'time' module stripped down to only the bare essentials that just don't fit in datetime and push everyone to use datetime for most things.

I realize the %4N notation is distasteful, but without it I think you will have trouble parsing something like
What would be the format string? %H:%M:%S.%N would be incorrect.
Why is that incorrect?
