In the future, on other patches, you should provide a rational for
*why* you are submitting this change, not what the change does.

As for this patch, it would be a bad change, as this changes the
established behavior that the repeating 59th second w/ the TIME_OOP
flag set is the 60th/leap second and would break any apps that care to
actually watch for the leap second. Your change would cause
applications that do not care about leapseconds which have timers set
to the 00:00:00 UTC to fire a second early.
