Since He inhabits the entire universe, I'm sure He measures time by the rotation and orbit of planet Earth.
How did God measure time before He created the universe?
If you want to know how old the Earth is...you must first know how God measures time.

How does God measure time?
Do you know?
No.
1) You have no reason to assert that God measures time in some way unknown to us. But in any case, it is illogical to assert that even if God "measures time" in some other way, that that would prevent us from measuring that time period.
2) God has clearly provided ample evidence of the age of the earth throughout his creation. We see this in a wide variety of DIFFERENT KINDS of evidence which all yield the same age. The age of the earth is not all that difficult to determine---and the Christ-follower need not fear the answers which God has provided in his creation.
3) So apparently God wished us to know the age of the earth. God's Bible doesn't focus on such questions but the Creation which God "authored" does.
4) It doesn't matter what "time unit" is used for the measurement as long as people understand the definition behind a particular standard. The orbital period of the earth around the sun (another of God's creations) has become a standard unit of time measurement and there is no reason to avoid it. (That is, unless someone has some sort of objection to how God established such phenomena in his creation, why contest it?)
Your inference that God (and perhaps the angels) have some alternative unit of time which they prefer to use is a figment of your imagination. You have no Biblical basis for the claim. And considering that the Bible says that God (a) exists outside of time, and (b) created time, it is a rather bizarre claim.
But EVEN IF angels in the presence of God know of some "time unit" which God has ordained, it would in no way contradict or nullify the various means of measuring time which God made provision for in his creation.
>"How could anyone ever figure out how old the Earth is without knowing how God measured time?"
That question leads me to wonder if you understand how the age of the earth can be determined. (If you did, you wouldn't make the assertions you've posted.) The username you've chosen appears to suggest that you have a high opinion of your own wisdom. But whatever the case, on this topic you are definitely giving the impression of being uninformed.
Your question reminds me of analogous questions like "How did United States citizens protect their voting rights in federal elections held during the third millennium B.C.?" Doesn't make any sense.

God does not measure time because he is infinite. Besides, why would He.
