copied!<p>Python's time.clock calls C function clock(3) -- <code>man clock</code> should confirm that it's supposed to work on BSD, so I don't know why it's not working for you. Maybe you can try working around this apparent bug in your Python port by using <code>ctypes</code> to call the clock function from the system C library directly (if you have said library as a .so/.dynlib/.dll or whatever dynamic shared libraries are called on FreeBSD)?</p> <p>time.time is supposed to be very high resolution, BTW, as internally it calls gettimeofday (well, in a properly built Python, anyway) -- what resolution do you observe for it on your system?</p> <p><strong>Edit</strong>: here's <code>wat.c</code>, a BSD-specific extension (tested on my Mac only -- sorry but I have no other BSD flavor at hand right know) to work around this apparent FreeBSD port problem:</p> <pre><code>#include "Python.h" #include <sys/time.h> static PyObject * wat_time(PyObject *self, PyObject *args) { struct timeval t; if (gettimeofday(&t, (struct timezone *)NULL) == 0) { double result = (double)t.tv_sec + t.tv_usec*0.000001; return PyFloat_FromDouble(result); } return PyErr_SetFromErrno(PyExc_OSError); } static PyMethodDef wat_methods[] = { {"time", wat_time, METH_VARARGS, PyDoc_STR("time() -> microseconds since epoch")}, {NULL, NULL} /* sentinel */ }; PyDoc_STRVAR(wat_module_doc, "Workaround for time.time issues on FreeBsd."); PyMODINIT_FUNC initwat(void) { Py_InitModule3("wat", wat_methods, wat_module_doc); } </code></pre> <p>And here's the <code>setup.py</code> to put in the same directory:</p> <pre><code>from distutils.core import setup, Extension setup (name = "wat", version = "0.1", maintainer = "Alex Martelli", maintainer_email = "aleaxit@gmail.com", url = "http://www.aleax.it/wat.zip", description = "WorkAround for Time in FreeBSD", ext_modules = [Extension('wat', sources=['wat.c'])], ) </code></pre> <p>The URL is correct, so you can also get these two files zipped up <a href="http://ttp://www.aleax.it/wat.zip" rel="nofollow noreferrer">here</a>.</p> <p>To build & install this extension, <code>python setup.py install</code> (if you have permission to write in your Python's installation) or <code>python setup.py build_ext -i</code> to write wat.so in the very directory in which you put the sources (and then manually move it wherever you prefer to have it, but first try it out e.g. with <code>python -c'import wat; print repr(wat.time())'</code> in the same directory in which you've built it).</p> <p>Please let me know how it works on FreeBSD (or any other Unix flavor with <code>gettimeofday</code>!-) -- if the C compiler complains about <code>gettimeofday</code>, you may be on a system which doesn't want to see its second argument, try without it!-).</p>
