    1.18 +* FUNCTION
    1.19 +* <<difftime>>---subtract two times
    1.20 +* INDEX
    1.21 +* difftime
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <time.h>
    1.24 +* double difftime(time_t <[tim1]>, time_t <[tim2]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <time.h>
    1.27 +* double difftime(<[tim1]>, <[tim2]>)
    1.28 +* time_t <[tim1]>;
    1.29 +* time_t <[tim2]>;
    1.30 +* Subtracts the two times in the arguments: `<<<[tim1]> - <[tim2]>>>'
    1.31 +* that are in seconds.
    1.32 +* RETURNS
    1.33 +* The difference (in seconds) between <[tim2]> and <[tim1]>, as a <<double>>.
    1.34 +* PORTABILITY
    1.35 +* ANSI C requires <<difftime>>, and defines its result to be in seconds
    1.36 +* in all implementations.
    1.37 +* <<difftime>> requires no supporting OS subroutines.
