Love it :) I think the "consistently connect to a projector" is similar. Moyle's Law seems popular here and has generated a great conversation, I'll raise it as a suggestion on the repo and see what people think!
EDIT: I see that you've submitted an RFC but it misses (what I think is) the point. It's really the corollary of the law that is important as it states how hard it is to do date/time correctly (and you'll notice that the bulk of the discussion here is on the corollary). As I noted above, this was intended to be funny and including it in a list with real laws is just that much funnier!
