A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1. 

The most recent one happened on June 30, 2012, at 23:59:60 UTC.

A leap second will again be inserted on June 30, 2015, at 23:59:60 UTC.

CA SYSVIEW takes into consideration the leap second table that is published in the IBM Principles of Operations manual.

CA SYSVIEW time calculations take into account the leap second offset in IBM control block CVT.

Maintenance is required for leap second support only if the Explore Report Writer component is used.

  • Customers using SYSVIEW r13.9 will need a PTF for Explore Report Writer leap second support.
  • Customers using SYSVIEW r14.0 will need a PTF for Explore Report Writer leap second support, or can manually specify the leap second change using Explore Report Writer option:

          OPTION(LEAPSEC=nn), where nn is the number of leap seconds. The number of leap seconds will increase by one, from 25 to 26, between June 30 and July 1, 2015.
