NAME
     difftime - computes the difference between two calendar
          times

SYNOPSIS
     #include <time.h>

     double difftime (timet time1, timet time0);

DESCRIPTION
     difftime computes the difference between two calendar times.
     difftime returns the difference (time1-time0) expressed in
     seconds as a double.  This function is provided because
     there are no general arithmetic properties defined for type
     time_t.
