    14 * Description:

    15 * FUNCTION

    16 * <<difftime>>---subtract two times

    17 * INDEX

    18 * difftime

    19 * ANSI_SYNOPSIS

    20 * #include <time.h>

    21 * double difftime(time_t <[tim1]>, time_t <[tim2]>);

    22 * TRAD_SYNOPSIS

    23 * #include <time.h>

    24 * double difftime(<[tim1]>, <[tim2]>)

    25 * time_t <[tim1]>;

    26 * time_t <[tim2]>;

    27 * Subtracts the two times in the arguments: `<<<[tim1]> - <[tim2]>>>'

    28 * that are in seconds.

    29 * RETURNS

    30 * The difference (in seconds) between <[tim2]> and <[tim1]>, as a <<double>>.

    31 * PORTABILITY

    32 * ANSI C requires <<difftime>>, and defines its result to be in seconds

    33 * in all implementations.

    34 * <<difftime>> requires no supporting OS subroutines.

    35 *
