Im guessing you mean in relation to realy time, you may want to use CLOCKS_PER_SEC to get things in terms of time and in terms of time to clocks for example divide clock()/CLOCKS_PER_SEC withh give you how many seconds, etc and if you want to wait for x seconds do seconds*CLOCKS_PER_SEC

The time_t type is an implementation-defined arithmetic type capable of representing times. Use difftime function to get the difference between two times of type time_t in seconds as a double value:

 Help with Code Tags 
 c Syntax (Toggle Plain Text) 
#include <time.h>
...
    time_t t;
    time(&t);
    printf("time_t step %f sec\n",difftime(t+1,t)); // time_t precision
#include <time.h>
...
    time_t t;
    time(&t);
    printf("time_t step %f sec\n",difftime(t+1,t)); // time_t precision

As usually, it's equal to 1 sec (but it's not the language standard requirement).
