Error description

  • Customer reports after dynamically switching to daylight saving
    time (GMT-2), Enterprise COBOL pgms using "ACCEPT FROM TIME"
    command (which invoke CEELOCT / CEEGMTO) continue to return
    previous time (GMT-3)
    
    Some PL/I functions that use CEELOCT / CEEGMT include date(),
    time(), datetime(), days(), and secs() may also be impacted.
    
    PE INFORMATION:
       Users Affected: Customers that are running with fixes for
       apar PI78252 ie PTF UI48801 / UI48802 / UI48771 AND invoke
       the CEELOCT or CEEGMTO LE callable services
    
       User Impact: APAR PI78252 fixed the problem it reported but
       introduced a new problem.  After time is dynamically
       changed, applications that invoke the CEELOCT or CEEGMTO LE
       callable services may continue to report previous time for
       example a DST adjustment made dynamically may not be reported
       correctly by such applications.
    

Local fix

  • OPTION 1: If the fixes for PI78252 have not been APPLIED to your
              system then DO NOT apply them. If they have been
              applied but NOT ACCEPTed, then you may back off (i.e.
              SMP/E RESTORE) the fixes.
              This action requires an IPL
    
    OPTION 2: You may install the appropriate level fix (++APAR) for
              PI89400 and IPL the system

Problem conclusion

  • The code change of PI78252 has been backed out in this APAR.
    Regarding to the problem reported in PI78252, a document change
    is delivered as below:
    Book: z/OS Language Environment Programming Reference >
    Part 2: Language Environment callable services >
    Chapter 5: Callable services >
    CEELOCT - Get current local date or time >
    Change the first usage notes as below:
    Usage notes:
    | * z/OS consideration - After issuing the MVS command SET
    | DATE, the output value returned by CEELOCT may not
    | represent an accurate date or time.
    Book: z/OS Language Environment Programming Reference >
    Part 2: Language Environment callable services >
    Chapter 5: Callable services >
    CEEGMTO - Get offset from Greenwich Mean Time to local time >
    Change the first usage notes as below:
