8.1 8.2

Description (partial)

There are periodic leap second events which can add or delete a second to global time. 

The Cisco Prime Network Registrar (CPNR) product does not have an issue with leap seconds.  However, the appliance / virtual appliance (OVF) uses a version of CentOS that does have leap second issues.  Customers should check the operating system they are using for CPNR (whether installed via the OVF or otherwise) and are highly encouraged to update their operating system if it is impacted by leap second issues. The CentOS operating system shipped with CPNR (8.1 and 8.2) is impacted by the leap second issue.

This CDET was created to track the following actions;
a.) New OVA with updated CentOS (6.5) to be bundled with the release 8.3, GA in March 2015. 
b.) New OVA with updated CentOS (6.5) to be bundled with latest maintenance releases for 8.1 and 8.2.

The leap second update will be propagated via Network Time Protocol (NTP) or via manually setting the clock.
