difftime(3C)        (C Programming Language Utilities)         difftime(3C)


   NAME
         difftime - computes the difference between two calendar times

   SYNOPSIS
         #include <time.h>

         double difftime (time_t time1, time_t 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.
