However, on Windows, time.clock() returns the actual time since it was first called. In the above example, the straight line is y = 205.91 x + 29.56; therefore, the execution time equals 205.91 milliseconds.. Time module in Python provides various time related functions.. time.clock() method of time module in Python is used to get the current processor time as a floating point number expressed in seconds.
I have tested that the issue is present in 3.6 and the offending code has been present since time.perf_counter() was introduced in 3.3. If secs is not provided or None, the current time as returned by time() is used. . It will let you watch memory usage and many other statistics of applications and the operating system. The monotonic() clock can be used to measure elapsed time in a long-running process because it is guaranteed never to move backwards, even if the system time is changed. The authors note that this type of measurement is very robust against occasional measurements with large errors. The overall execution time can then be obtained by taking the slope a from the straight line y = a x + b.. I'm not sure this code does what you think it does, at least on a *nix OS. Summary: The Python win32pdh module simplifies access to Windows performance counters, the same ones perfmon shows.
Hi Terry, I'm new to this so apologies in advance if this is a silly question...can you explain why you removed 3.5 and 3.6 from the versions list? The Python module isn't well documented, though, so this article shows some sample code and describes its functions in more detail. time.clock() method also call C library function of the same name to get the result. The standard system calls like time() report the system “wall clock” time. time.perf_counter returns the absolute value of the counter. If secs is not provided or None, the current time as returned by time() is used. As, Most of the functions defined in time module call corresponding C library function. According to the documentation, time.clock() returns processor time, which basically means that any time spent in time.sleep() is not counted. The time module provides access to several different types of clocks, each useful for different purposes. Python time method ctime() converts a time expressed in seconds since the epoch to a string representing local time.
