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.
 

He was a real person, even if some of the details and more supernatural aspects are arguably still up for interpretation. His main adversaries didn't say he didn't exist, rather they didn't believe what was said about him (or that he was the one that the prophecies had been written about).
Then again, it is very well possibly he could reappear again in the not too distant future, and if so, better to not be on his bad side. Though, the specifics of all of this are also still up for interpretation.
But, will note that, yeah, the Earth and universe have lifespans measured in billions of years, as there are just too many "deal breaking" science issues with trying to claim that it is 6000 years.
Well, and life was less "poof, everything now exists" and more a whole lot of copy-paste with the occasional intervention or edit now and then. Well, and the occasional "well, take this one thing, shuffle all the DNA around between its respective chromosomes, and now it is its own thing." and a few oddball animals seemingly with DNA from all over the place.
So, maybe something is going on, even if the specifics are a little fuzzy.

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.

Seems pretty reasonable.
Also if people spread to multiple planets, they may or may not have reason to care about the (arguably small) drift in local time relative to Earth due to relativistic effects.
Then again, say, if you have a 20 minute round-trip time for communication, a few milliseconds per year of clock-drift, or time measurement deviations due to red and blue shifts between planets, may not matter all that much...
Granted, may matter more on the Moon, which would have a larger relative skew due to the differences in planetary gravity, and round-trip time small enough to allow (more or less) real-time communication.
Well, even if the internet experience would rather suck with around a 2600ms ping time... But, I once lived in a place where internet ping times were pretty much this bad.
