PH12911: CEELOCT FAILS TO RETURN A VALID TIME WHEN CVTLSO IS NEGATIVE.

APAR status

• Closed as fixed if next.

Error description

• LE's CEELOCT service is used to give an application the current
  time in multiple formats.  This service takes into account the
  number of leap seconds specified on the
  system.
  
  When the system has a negative Leap Second value (CVTLSO), the
  resulting date returned can be either 1876/09/16 or 2076/09/16.
  
  ANALYSIS:
  When the leap seconds value is negative, the calculations done
  by internal routine CEEYGMT shifts the value incorrectly.
  
  KNOWN IMPACT:
  Applications that use CEELOCT will have invalid timestamps.
  
  VERIFICATION STEPS:
   - the application is using CEELOCT,
   - the system has a negative Leap Second value
  

Local fix

• BYPASS/CIRCUMVENTION:
  Change the Leap Seconds value on the system.  Possible options
  are 0 or 27 (the international standard since Dec 31, 2016).

  * Users of 31-bit Language Environment applications that use   *
  * interfaces CEEGMT and CEELOCT and set leap second to         *
  * negative value.                                              *
