Original Document Release.

In June 2012, the International Earth Rotation and Reference Systems Service (IERS) introduced a leap second to the Coordinated Universal Time (UTC). A leap second is a one-second adjustment that is occasionally applied to UTC. The IERS will introduce another leap second to UTC on December 31, 2016. HPE is aware of this occurrence and has confirmed that HPE ProLiant servers are not impacted by the introduction of a leap second. Because the aspects impacting the need for leap seconds vary in response to climatic and geological events, leap seconds are irregularly spaced and unpredictable. As such, HPE ProLiant servers do not automatically adjust to leap seconds.

DETAILS

When a leap second is introduced, the next update from a network time server (if used) will correct any discrepancy with the server's hardware clocks. This is performed with the Network Time Protocol (or similar) to remain in synchronization with UTC. When the leap second was introduced on June 30, 2012, some computer systems experienced technical problems due to an issue with how the Linux operating system handled the Network Time Protocol's introduction of the leap second. These issues have been addressed in updates to the Linux operating system. For additional information on the effects of the leap second on the operating system, refer to the operating system vendor.

NOTE: If a server is not running a network time server, the clock can be manually adjusted for the leap second after it occurs to allow the system to stay in synchronization with UTC.
