I wrote a script that does some time measurements. It uses
time.perf_counter() from Python 3 which works very well. Now I need to
backport it to python 2.
Docs say that time.clock() is way to go:
On Unix, return the current processor time as a floating point number
expressed in seconds. The precision, and in fact the very definition of the
meaning of “processor time”, depends on that of the C function of the same
name, but in any case, this is the function to use for benchmarking Python
or timing algorithms.
On Windows, this function returns wall-clock seconds elapsed since the first
call to this function, as a floating point number, based on the Win32
function QueryPerformanceCounter(). The resolution is typically better than
But for me it always returns the almost same number, nothing time like:

[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
What's wrong there?
