Full ACK.

There is an unfortunate history of critical-to-moderately-serious bugs in
the leap second handling, so I submit that what is needed is a simple,
obviously-correct and robust mechanism. Robust statically, but also in the
face of code churn because these code paths are exercised so rarely out in
the wild.

Just my opinion, FWIW.
