But now I'm wondering, will NTP pickup the change at 8:00p EDT? Or
must I do something to catch the change?
From http://www.ntp.org/ntpfaq/NTP-s-algo-real.htm#AEN2499
*5.3.4.*What happens during a Leap Second?
The theory of leap seconds in explained inQ: 2.4.
<http://www.ntp.org/ntpfaq/NTP-s-time.htm#Q-TIME-LEAP-SECOND>. In
reality there are two cases to consider:
*
If the operating system implements the kernel discipline described
inSection 5.2
<http://www.ntp.org/ntpfaq/NTP-s-algo-kernel.htm>,*ntpd*will
announce insertion and deletion of leap seconds to the kernel. The
kernel will handle the leap seconds without further action necessary.
*
If the operating system does not implement the kernel discipline,
the clock will show an error of one second relative toNTP's time
immediate after the leap second. The situation will be handled just
like an unexpected change of time: The operating system will
continue with thewrongtime for some time, but
eventually*ntpd*willstepthe time. Effectively this will cause the
correction for leap seconds to be applied too late.
