There have been some strong views expressed that a day has to mean a
solar day, i.e. midnight-to-midnight (or midday-to-midday).
A basic component of the dispute is The time that people have agreed
upon. Leap seconds persist now
Oh dear, my ears are burning.
The leap second debate is all about social custom. It is about definitions
(which are social customs) used by people (which is social) and decided by
international bodies of experts (which involve social relationships and social
processes) that will determine

There must be thousands of source files with stale leap second tables

Is there any solution to this?
For those who think ahead, the obvious solution is that every leap second
table (hard-coded or otherwise) must include data showing the limits of
its validity, and all code

Surely it would be better to allow civil time to run smoothly from
atomic clocks, and give ourselves a few hundred years to quietly consider
how to correct the slow drift that has reached the same order of magnitude
as the analemma effect, which we regularly ignore
Yes, both solar time and atomic time are based in physical reality. That’s the
point as made innumerable times on this list. Civil time is derived from two
distinct clocks. Solar time defines the day. Atomic time defines the second
(fundamentally it is a frequency standard). There are
