Whether the leap-second flag means "end of the current day" (per RFCs
1305 and 4330) or "end of the current month" (per the draft RFC for NTP
v.4), indicating a leap-second today is an error.  When such an error is
seen, it makes me question the accuracy of the affected NTP server.
After all, if they can't get the leap-second flag correct (something I
dealt with in the early 1970s before there was NTP), what else are they
doing wrong?

By the way, the draft RFC expires in a little over a month from now.
