Linux ntpd leap second preparation

There will be a leap second on June 30, 2015 at 23:59:60 UTC.

I have a Linux based stratum 1 NTP server which uses GPS as a reference clock. The server is using the "default" ntp.org ntpd.

How should I prepare for the leap second to ensure that the correct time is available at and after the leap second?

Will the ntpd server behave correctly?

If uncertain, is there a way to test this beforehand?

Solution 1:

There is some explanation here

Looks like you will need to check the kernel settings etc and if all is in order ntpd will take care of things. Your application layer might need more thought though.
