difftime - computes the difference between two calendar times
#include <time.h> double difftime(time_t time1, time_t time0);
The difftime() function computes the difference between two calendar times.
The difftime() functions returns the difference (time1-time0) expressed in seconds as a double.
The difftime() function is provided because there are no general arithmetic properties defined for type time_t.
