AFAIK, that's irrelevent.  time.time() returns a float.  On all the
CPython implementations I know of, that is a 64-bit IEEE format, which
provides 16 decimal digits of precision regardless of the granularity
of the system time value.  At this point in time, that means 10 digits
left of the decimal point and 6 to the right.
