I'm not talking about JSR-310, I'm talking reality.

Thanks to leap-seconds we do not know how long (certain) minutes
are, until Daniel tells us.

By extension it follows that we do not know how long the hours,
days, years, decades, centuries & millenia which ocntains one of
these minutes are.

"UTC is unpredictable" is the core of the problem, and a problem
that must be solved, either by extending the predictability horizon
from six months to at least 10 years, or by making UTC predictable.
