I've found my own Jeeves clock to be curiously eccentric.

He no longer keeps the time faithfully, although he does go off - twice a day, morning and evening, around 7. How he can tell it is 7, I do not know.

On these occasions, his behaviour is erratic - sometimes he'll only go off once, sometimes three or four times in quick succession. And he'll beep, sometimes only twice, other times 20 times.

I think he's been into the snuff.
