Huh? Am I getting my days wrong?

I think there's something really wrong with Facebook. Can you spot it?

exhibit no. 1

exhibit no. 2

Saw it? I don't think I'm crazy and I don't think I'm seeing things wrongly too.

Yesterday = the day before today (past)
Today = present day
Tomorrow = the after today (future)

So I ask you now: How can your comment be there before the day comes?

I tak faham. You faham? Tolong jelaskan kepada saya.

Terima Kasih.
