Interesting, didn't know about this function...

       #include <time.h>
       double difftime(time_t time1, time_t time0);
...
       This  function  is required by ANSI C.  On a POSIX system, time_t is an
       arithmetic type, and one could just define
              #define difftime(t1,t0) (double)(t1 - t0)

Doesn't look too encouraging.
