Because what happens at the subsecond level is not well-defined,
and insofar as it is well-defined, it is not well-implemented.
Theoretically the repeat happens exactly at the change from 23:60
to 23:61, but NTP does it several fractions of a second later.
I don't know half of you half as well John Cowan
as I should like, and I like less than half cowan at ccil.org
of you half as well as you deserve. http://www.ccil.org/~cowan
