[ntp:questions] How to insert a leap second with ntpq

Hi again David,

I ran your Leap Trace program against my gps-based time servers and not one is showing a leap second pending.  Not even this one that is leap-second configured.

GPSCON is showing a leap second pending on my HP Z3801.

This is very mysterious.

With all this discussion of leap-seconds, perhaps it's timely to mention my 
simple tools for leap-second checking across servers.  You will find NTP 
Leap trace here:


At this instant, fewer than 1 in 10 of the remote servers I'm using are 
indicating a pending leap second, and we are 9 days away from the event.  I 
can't recall now how long before the event it should be announced by typical 
NTP servers.
