Does that support the other way -- or do we never lose a leap second
anyway? (showing ignorance here)
But still, now datetime *could* support leap seconds (which is nice,
because before, 23:59:60 was illegal, so it couldn't even be done at all),
but that doesn't mean that it DOES support leap seconds....
