Try this:

Code:

#include <sys/time.h>

int main()
{
   timespec ts;
   clock_gettime(CLOCK_REALTIME, &ts);
}

thank you.

I tried but I am getting "undefined refrence to 'clock_gettime()'. I see someother people have the same issue. I read in another thread :
http://www.linuxquestions.org/questi...roblem-390051/

that I should include with -lrt. Could you help me undresntad this? should I include this in mu make file?
