The point is, the uncertainty in the date of his birth, whether
fictional or real, is far less than the 59 million year uncertainty in
the date of the Big Bang. In order for it to be comparably uncertain, we
would have to be unsure whether he was incarnated in the Mesozoic or
Cenozoic eras.

None of that is relevant.

The uncertainty in the timing of the Big Bang and the birth of Christ
are relevant to cosmologists, historians, and religious scholars, not
to programmers who don't happen to be working in any of those fields.

The uncertainty in the timing of January 1, 1970, where 1970 is a
year number in the current almost universally accepted Gregorian
calendar, is essentially zero.  Same for any other less commonly
used chosen epoch.  The fact that the number 1970 is arbitrary
is not a problem for software.  In fact it's an advantage, since
there's no uncertainty in the presence of any new information.
