Leap-seconds, as implement, are unworkable. You can see long messages
from me in the past enumerating the reasons relating to systems,
especially systems disconnected from the internet...
Leap-seconds, the concept, have a limited shelf life. Maybe only a
few thousands years. So there's nothing really to preserve. One day
they must be abandoned.
As soon as we fixed the length of a second based on atomic behavior
rather than as 1/86400th of a mean solar day, we really abandoned time
based on mean solar time. Leap seconds are at best a hack to paper
over this fundamental decision.
