Without wishing to downplay the problems you are having with the
Java API, the 23:59:60 notation cannot be said to be a fundamental
problem with UTC itself in the sense I intended. After all, you
have designed the API for classes that do handle UTC properly.
In the same vein, representing UTC in Julian Date form is a
problem, but not fundamental in any sense. The API of the SOFA
library shows one way of handling it - http://www.iausofa.org/ .
Representing the 61st second on an analogue clock face is another
problem, again not fundamental - solutions can be found.
