difftime(3C)                                                   difftime(3C)

NAME
     difftime - compute 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. diff-
     time() returns the difference (time1-time0) expressed in seconds as a
     double. This function is provided because there are no general arith-
     metic properties defined for type timet.
