small hours

If it is already tomorrow, but it is the small hours and you have not yet slept, does putting up a post count as tomorrow's post or yesterday's?  And does it in any case count as a post to say that it is already tomorrow and you have not yet slept? I would say yes.  Especially as I did not post yesterday, which is still today as it does not really become tomorrow until there has been a period of sleep between now and then.  So what I have come here to say is that although it is tomorrow it is actually still yesterday, or it is neither and I am therefore sitting inside the Tardis otherwise known as Signs Cottage wondering if I still exist or whether I slipped into a black hole between the stroke of midnight and the second that followed.  That is not actually what I have come here to say.  But let it stand, because the fact of my saying anything at all is a) proof that I do in fact exist and b) counts as yesterday's post.  So I am still on track.  And anyone who wants to argue with that is, in fact, a mashed potato.  Thank you.
