+* FUNCTION
+* <<difftime>>---subtract two times
+* INDEX
+* difftime
+* ANSI_SYNOPSIS
+* #include <time.h>
+* double difftime(time_t <[tim1]>, time_t <[tim2]>);
+* TRAD_SYNOPSIS
+* #include <time.h>
+* double difftime(<[tim1]>, <[tim2]>)
+* time_t <[tim1]>;
+* time_t <[tim2]>;
+* Subtracts the two times in the arguments: `<<<[tim1]> - <[tim2]>>>'
+* that are in seconds.
+* RETURNS
+* The difference (in seconds) between <[tim2]> and <[tim1]>, as a <<double>>.
+* PORTABILITY
+* ANSI C requires <<difftime>>, and defines its result to be in seconds
+* in all implementations.
+* <<difftime>> requires no supporting OS subroutines.
