comment How are CPU time and CPU usage the same?
@MichaelHampton: I think maybe this starts to explain it: man7.org/linux/man-pages/man7/time.7.html . On my CentOS system CONFIG_HZ=1000 , and /proc/stat does return things in 1/100 of a second. So it seems like maybe the tick interval of the kernel and user space reporting may not be the same.

@MichaelHampton on CentOS 6.5 sysconf(_SC_CLK_TCK) returns 100, am I missing something?
