DIFFTIME(3C)            STANDARD C LIBRARY           DIFFTIME(3C)


NAME
     difftime  --  compute  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.
