Description

Leap Second Change

Scope
Version: All CentOS Systems
Solution

Version: all CentOS Systems

Issue: Is the Bradford Agent going to have an issue with Leap Second?

Solution:

Systems should automatically account for leap second corrections if they are using the NTP (Network Time Protocol) daemon to synchronize their local timekeeping with an NTP server.

For systems not synchronized by NTP, it is recommended to install the latest OS updates to ensure that tzdata-2015a-1.el5 or later is installed so that this leap second may be inserted.

There was the potential for the kernel to hang, but that was addressed in kernel-2.6.18-131 which was fixed prior to CentOS 5.4 so it should not affect any of our customers.
