Miss clock_gettime

[845767657 at qq.com]

Hello,
I want to lean what's the python time.time do?
Using strace, I cannot find anything about time system call.
so I write a simple C snippet that just call clock_gettime(2), but
also strace didn't trace it.

---------------------
#include <unistd.h>
#include <time.h>

int main()
{
    struct timespec ts;
    clock_gettime(CLOCK_REALTIME, &ts);
    return 0;
}
-----------------------


$ strace -V
strace -- version 4.21
