God, and Jesus DEFINE Themselves as outside of time, unequivocally.
Their self-description as "I AM" clearly declares Them and Them alone to be the only Beings who exist eternally in the present. Who consequently know the end from the beginning.
Exo 3:14
And God said to Moses, “I AM WHO I AM.” And He said, “Thus you shall say to the children of Israel, ‘I AM has sent me to you.' ”
Jhn 8:24
I said therefore unto you, that ye shall die in your sins: for if ye believe not that

Jhn 8:58
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was,

Rev 1:8

Rev 22:13
I am Alpha and Omega, the beginning and the end, the first and the last.

BTW.......God never needs new information......He has all of it already. Which is why Jesus is the ONLY One who can judge the world in perfect righteousness. He and the Trinity alone know everything there is to know about everything and everyone.

Gen 1:14
And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
