Content
The pyc format currently stores the modification time cast to a 32-bit int. A 3.3 iteration of the pyc format could instead store two 32-bit ints, one for the integral part and one for the fractional part (e.g. in nanoseconds). When HAVE_STAT_TV_NSEC is defined, struct stat has a "st_mtim" member which is a struct timespec providing theoretical nanosecond precision. Whether this would be useful remains to be decided.
