What does "call home" mean?

When you call a building home you would mean that the building is your home. Is that what the "call home" means in the context below?

Context:

The question itself predates modern cosmology by at least 1,600 years. Fourth-century theologian St. Augustine wrestled with the nature of God before the creation of the universe. His answer? Time was part of God's creation, and there simply was no "before" that a deity could call home.
Armed with the best physics of the 20th century, Albert Einstein came to very similar conclusions with his theory of relativity. Just consider the effect of mass on time. A planet's hefty mass warps time -- making time run a tiny bit slower for a human on Earth's surface than a satellite in orbit. The difference is too small to notice, but time even runs more slowly for someone standing next to a large boulder than it does for a person standing alone in a field. The pre-big bang singularity possessed all the mass in the universe, effectively bringing time to a standstill.
