Neither is that of some fictional religious entity.

Not true. While his divinity is fictional, there might have been a
person who was the inspiration for those stories. Whether or not he was
real, the stories of his life are only consistent with a very specific
time period, which narrows the time period of his (possibly fictional)
birth to within just a few years. The uncertainty in the timing of the
Big Bang is currently about 59 million years.

On 1977-01-01, international time keepers started correcting for the
fact that different atomic clocks measured time at different speed
because they were at different altitudes. As a result, that date is
epoch used in Barycentric Coordinate Time (TCB), Geocentric Coordinate
Time (TCG), and Terrestrial Time (TT). I would therefore favor that
epoch over any other that I can think of.
