Sorry but you can only have time zero if you are accepting the something from nothing scenario of the Standard Model (I don’t); all other time zero references are as you say, on a sliding scale; is the BB event time zero an absolute? I think not; it is only the best promoted one at this time. We just need a good reason to modify it!

Now as for singularities, they fall into the same category as strings and gods; all theory and no evidence.

The asymptotic nature of mathematics is why it is an abstract concept that can produce false observations and concepts. Scientists should not put their heads too far up their math and lose sight of reality; too many have done that already and caused unbelievable confusion.
