With the pure Python code below, I get results like: micro sec: 1.0 12.2 154.8 micro sec: 0.9 11.3 156.0 when requesting 0, 10 and 160 us, which seems reasonable - PII600 Win2K Py2.2.
On Linux with a 2GHz Py2.3 it seems to always return 0.0
Right. On Linux, time.clock() has a precision of 10 ms. None of your calls take more than 10 ms, so the difference is always 0.
I can't tell what you're trying to achieve with this code. time.clock() returns very different things on Windows and Linux. On Windows, it returns (roughly) real time since the beginning of the process. On Linux, it returns CPU time used since the beginning of the process. Since sleep() does not use CPU time, clock() stops while you sleep.
What are you trying to achieve? Python is almost certainly the wrong approach for a real-time process.
