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 timet.
