PM17868: CEMT INQUIRE CLASSCACHE DOES NOT DISPLAY THE CORRECT DATE AND TIME.

Obtain the fix for this APAR.

APAR status

• Closed as unreproducible.

Error description

• You have noticed that the start time and date issued by CEMT
  INQUIRE CLASSCACHE is later than the current time and date.
  .
  The sjvms_start_abstime field should contain the local
  classcache start time. However, this contains a GMT time instead
  .
  This is formatted by DFHTIMF as part of CECI FORMATTIME. DFHTIMF
  assumes it being passed a local time. This gets displayed in
  both local time (which is incorrect as the value stashed in
  sjvms_start_abstime is GMT) and GMT (which is also incorrect as
  DFHTIMF performs an adjustment on what it assumes is a local
  time).

  When a CLASSCACHE is started DFHSJCC does a call to DFHTIMF
  for INQUIRE_TIME to get the local time in abstime format.
  In DFHTIMF the inquire_time routine does a STCK, which returns
  the TOD without any zone adjustment, then adjusts to local time
  by adding CVTLDTO. It then converts the resulting value to
  an abstime format, which means the number of milliseconds
  since 00:00 hours on 1 January 1900.
  Inquire_time then calls format_time to get the time into all the
  possible formats that the inquire_time might have requested.
  Format_time tests whether GMT was specified and if not it
  subtracts CVTLDTO from the abstime, resulting in an abstime
  value that is now incorrect by the CVTLDTO amount.
  This value is returned to DFHSJCC and is stored in the
  sjvms_state control block (the state information for the JVM
  set).
  Later the user does CEMT INQUIRE CLASSCACHE. This results in
  a DFHSJISM INQUIRE_CLASSCACHE requesting the start_time.
  To get the start_time it passes the incorrect abstime value
  from the sjvms_state control block as input to a DFHTIMF
  FORMAT_TIME call.
  This call executes the same format_time routine as
  inquire_time did, so it again tests if GMT was specified and
  if not it again incorrectly adjusts the abstime by CVTLDTO.
  The resulting abstime is now incorrect by twice the value of
  CVTLDTO. This value is used when formatting the time resulting
  in an incorrect value for Timestarted.
  The incorrect classcache start time stored in the sjvms_state
  block results in two additional problems:
   - EXEC CICS INQUIRE CLASSCACHE STARTTIME will return
     an incorrect ABSTIME value.
   - The report produced by the DFH0STAT sample statistics
     program shows an incorrect value for 'Class Cache start
     date/time'. DFH0STAT is executed via the STAT transaction.
  

Problem conclusion

Temporary fix

• FIX AVAILABLE BY PTF ONLY
  

Comments

• DFHTIMF has been altered to set an indicator before the call to
  format_time to indicate that this call does not require any
  adjustment to the abstime. The format_time routine
  will now test the new indicator and bypass the code to adjust
  the time if set.
  DFHSJIS has been altered to specify ZONE(GMT) on the call
  to DFHTIMF for FORMAT_TIME. This prevents format_time from
  doing any adjustment to the abstime.
