Message 88070 - Python tracker (original) (raw)

time.clock() is a simple wrapper around the C stdlib clock() function. As the clock() man page says:

« Note that the time can wrap around. On a 32-bit system where CLOCKS_PER_SEC equals 1000000 this function will return the same value approximately every 72 minutes. »

Is it a 32-bit or 64-bit Python build? (you might have a 32-bit build on a 64-bit system) If it is a 64-bit build, what are sizeof(clock_t) and CLOCKS_PER_SEC on a your system? You can compile the following small C program to get the answer.

#include <stdio.h> #include <time.h>

int main(int argc, char **argv) { printf("sizeof(clock_t)=%d, CLOCKS_PER_SEC=%d\n", sizeof(clock_t), CLOCKS_PER_SEC); return 0; }
