Not sure what you think the problem is. The leap second notification is sen=
t
out by NIST I beleive, and the various sources will send it out as pat of t=
he
ntp packet. Change to leap second has nothing to do with your machine. If y=
ou
unplug it, then there is no way your machine can know what the leapstatus i=
s.=20
so why should it change it. Note also if your machine is unplugged it canno=
t
know what the time is, except from itself.
