This article provides information on Odin family products and leap seconds.
Leap seconds are a periodic one-second adjustment of Coordinated Universal Time(UTC) in order to keep a system's time of day close to the mean solar time. However, the Earth's rotation speed varies in response to climatic and geological events, and due to this, UTC leap seconds are irregularly spaced and unpredictable. This article seeks to provide information regarding the leap seconds themselves, along with addressing how Red Hat Enterprise Linux handles the insertion of one.
Upcoming Leap Second Events
The next leap second insertion is scheduled for June 30th, 2015 at 23:59:60 UTC.
To avoid any kind of issues please install all the OS updates.
As it is described in RedHat knowledge base the following issues can be faced:
Issue 1: Operating system can hang after insertion of leap second.
Restart server. Plese see related article in RedHat knowledge base: https://access.redhat.com/solutions/154713
Issue 2: Some heavy applications such as Java or Database servers can begin consuming a large amount of CPU.
This can be fixed by restarting the affected application. Plese see related article in RedHat knowledge base: https://access.redhat.com/solutions/154793
