Beginning of what?
If time did not exist, then nothing existed before. It's meaningless to speak of beginning when ti comes to God.
Beginning of what?
As I said, "before the foundations". God knew His children before He created the Heavens and the earth, etc. We are not told much about what God was up to before He created, but this the Bible tells us.

I don't know when God created time. All we know for sure is that it was some time before Gen. 1:1 because God did not come into existence at that point. God preceded creation, as we know it.
