 os.stat() uses float timestamps by default since Python 2.5. Python 3.3
 introduced functions supporting nanosecond resolutions:
 
- * os module: stat(), utimensat(), futimens()
- * time module: clock_gettime(), clock_getres(), wallclock()
+ * os module: futimens(), utimensat()
+ * time module: clock_gettime(), clock_getres(), monotonic(), wallclock()
+
+os.stat() reads nanoseconds fields of the stat structure, but returns
+timestamps as float.
 
 The Python float type uses binary64 format of the IEEE 754 standard. With a
 resolution of 1 nanosecond (10\ :sup:`-9`), float timestamps lose precision for values
