"No one" is used by Jesus (and evidently John), as you yourself cite, to refer to the entirety of creation - anyone who is not the omnipotent God:

>**Matthew 24:36** But of that day and hour **no one [οὐδεὶς]** knoweth: not the son, nor the angels of heaven, but only the Father.

Therefore, it necessary, or at least possibility, excludes God.
