Well at least the datetime library would be a perfectly reasonable place to handle leap seconds. The place that outputs the timestamp to a human readable format wouldn’t at all be that hard pressed to add a second when printing out the local time with timezone considered. It really wouldn’t add that much complexity.

Could you imagine if anyone was stupid enough to think the right place to handle such a thing was the internal counter of seconds rather than the datetime library though? Ha! That’d be ridiculous right! Imagine all the bugs if someone put something that’s only relevant to local timezone time printing there! It’d cause so many unexpected bugs!

Am I misreading something, or isn't that already in 1,000 years?

At 10^78 years we could use 512 bit time stamps and be safe from overflow and measure all the way down to Planck time.

Time is so /weird/ that I don't know how computers will ever wrangle it comprehensively.

Just consider the weird but valid scenario in relativity where A can occur before B, B before C, and C before A. I'm not sure how you would wrangle something like that in a data format.

Insertion of a leap second every month.

For dramatic effect, my monitor turned off right after "By this point, distant galaxies and starts are receding so fast that their light has become undetectable."

The "no more strength, no way out" part kills me every time I watch it.

Seems like unproven mumbo jumbo after about the halfway point

That or existential dread.

The only reason that the subsurface rock is cooler than magma is being able to conduct heat through to a cooler surface. When that surface becomes exterminatingly hot and remains so for a while the subsurface will be heating up too. Since the sun is estimated to remain a red giant for about one Gy it will become hotter than the surface.

1 Gy ago, life wasn’t multicellular.

I don’t think we have the ability to meaningfully predict such scales.

At that scale of time, it's not implausible that we have the technology to relocate Earth itself by then (e.g. increase its orbit).
