Time is part of the Creation, not a property or restriction on the Creator.
For instance, Jesus is the Lamb slain from the foundation of the world. He is always the Lamb of God, thus His sacrifice is perfection. Unlike the blood of a mere mortal, His blood never fades, never fails, never runs out.
And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. - Revelation 5:6
For by one offering he hath perfected for ever them that are sanctified. - Hebrews 10:14
Notwithstanding translations, the bottom line is that God's Name I AM is Truth regardless of when, or in what language, He announced that Name to us mere time-bound mortal creatures.
To God be the glory, not man, never man.
God is outside of time but man is not.
Now Jesus is not only true God, He is also true man. Thus, when the Second Person of the Trinity took upon Himself our humanity, He was born into time. He was born "at the fullness of time", as Scripture says.
Jesus is not outside of time by virtue of His human nature. He did not exist from all eternity for it required Mary's "yes" to bring about that union of God and man. Without Mary's "yes", there is no Jesus.
Thus OT times "predate" Jesus. They do not predate the second person of the Holy Trinity who is one with the Father.
