Dear CA Customer:


The purpose of this Advisory is to share information pertaining to the 2016 leap second event.  Leap seconds can be added in UTC at the end of June or December, depending on the evolution of UT1-TAI.  Per IERS Bulletin C 52, a new leap second will be added on December 31, 2016 23:59:60 UTC.  


PRODUCT(S) AFFECTED:                                                 RELEASES:


CA Workload Automation AE (AutoSys)                           11.0, 11.3, 11.3.5, 11.3.6

CA Workload Automation DE (dSeries)                            11.3, 11.3 SP1-SP3, 12.0, 12.0 SP1





All CA Workload Automation AE (AutoSys) and DE (dSeries) date and time operations are completed through Operating System function calls. Thus, the additional leap second will not affect the operation of CA Workload Automation AE (AutoSys) and DE (dSeries) nor any of the associated components provided the host operating system handles the leap second correctly.


As a reference, there were no reports of adverse impact to Workload Automation AE (AutoSys) and DE (dSeries) during the most recent leap second additions on June 30, 2015 (Bulletin C 49) or on June 30, 2012 (Bulletin C 43).


CA recommends keeping up to date on time and date related patches for your Operating Systems.  Please contact your Operating System vendor for more information.

Thank you,

CA Workload Automation Team
