Hi,

I think that should help:

Simply use clock(), it also uses the BIOS clock tick or use uclock() that also
(I guess) read the timer counter from the 8254  to get a better resolution.
To get the time in seconds just subtratec two times and divide by
CLOCKS_PER_SEC (or UCLOCKS_PER_SEC in case of uclock()).

#include <time.h>
.
.
.
clock_t t1, t2;
float tseconds;
.
.
.
t1 = clock();
.
.
.
t2 = clock();
tseconds = (t2  - t1) / (float)CLOCKS_PER_SEC;

Don't forget that BIOS timer tick have a resolution of 55ms (18.2Hz).
