It's an extra field in the structure returned from `decode-time'. There
may be callers that rely on it being exactly 8 elements... But I don't
think that's very likely? Hm... I guess I could see people saying
stuff like
(destructuring-bind (....) (decode-time)
)
and that would break, but on the other hand, you don't see many people
using those constructs in Emacs Lisp code.
We could add an optional parameter to `decode-time'
INCLUDE-FRACTIONAL-SECONDS and only include the 9th element then. But I
think we'd then basically would want to change all callers in Emacs to
include that parameter.
That's a safer option, though.
Either is fine with me.
