Physics, Astronomy & Cosmology / What time frame is used for the early universe (shortly after the "Big Bang")?

When cosmologists say things like "Approximately 10 to the −37 seconds into the expansion, a phase transition caused a cosmic inflation, during which the Universe grew exponentially" what time frame of what hypothetical observer are they using?
Since time varies according to gravity, and the universe shortly after the big bang was very small and dense, does that mean that time right after the big bang was moving slower (compared to our own time under 1 g)?
Are cosmologists using the 1 g time frame when describing the early universe?
Maybe I'm asking a stupid question, but I'm just wondering what the relativistic implications are considering how dense and massive the early universe was.
