Well, I didn't say that that NTP, and Mills and Levine themselves,
currently form a timekeeping model self-consistent with UTC, rather I
was trying to suggest that POSIX wasn't the only game in town. I've
made more successful rhetorical choices...

What is correct is to have a 61 second minute occasionally, neither
to redo the first second of the next day, nor to repeat the last
second of the current day.

Presumably no one would object if the ITU made it easier to obtain a
copy of 460.4.
