  On CICS Transaction Server V3 R2 or higher, PTFs were
  issued which shipped a new option of IMMEDIATE to be coded
  against the AUTORESETTIME SIT parameter.  This new parameter
  was part of the solution to a timing problem that existed at the
  aforementioned releases but not this release ( CICS TS V3R1 ).
  
  However, AUTORESETTIME=IMMEDIATE ensures that CICS and MVS
  System clocks are automatically coordinated at CICS task attach
  and has advantages over existing mechanisms.  This apar
  makes available,  the AUTORESETTIME=IMMEDIATE function to
  users of CICS V3 R1.
  

Problem conclusion

• CICS task attach logic has been amended such that if a new
  AUTORESETTIME parameter of IMMEDIATE is coded then the CICS
  internal clock ( in CSATODP ) will get reset immediately when
  DFHAPIN detects a mismatch between the MVS and CSATODP times.
  
  The following documentation changes will be made:
  
  The CICS Transaction Server for z/OS Version 3 Release 1 System
  Definition Guide (SC34-6428-08) will be updated, the
  description for AUTORESETTIME will have an additional option
  of IMMEDIATE added and will now read as follows:
                                                                 .
  AUTORESETTIME
   The AUTORESETTIME parameter specifies the action CICS should
   take for automatic time changes.
   AUTORESETTIME= IMMEDIATE|NO|YES
                            --
     Valid values are as follows:
     IMMEDIATE
          CICS will issue a PERFORM RESET command to
          synchronize the CICS time-of-day with the system
          time-of-day if, at the next task attach, the CICS
          time-of-day differs from the system time-of-day.
  
     NO   CICS issues message DFHAP1500 to indicate that a CEMT
     --   PERFORM RESET command is required to synchronize the
          CICS time-of-day with the system time-of-day.
                                                                 .
     YES  CICS issues a PERFORM RESET command to synchronize
          the CICS time-of-day with the system time-of-day
          if, at the next local midnight, the CICS time-of-day
          differs from the system time-of-day by more than
          30 minutes; for example, setting clocks forward or
          back to adjust for summer and winter time.
                                                                 .
  The CICS Transaction Server for z/OS Version 3 Release 1, Data
  Areas manual (GC34-6902-03 ) will be updated, as follows:
  
  The CSA will have 2 new fields added to byte CSAICIND thus:
  
  .... 1... CSAICIMM      IMMEDIATE specified on AUTORESETTIME
  .... .1.. CSAICRIP      Reset in progress
  
  
  Dsect TCADY ( the System TCA ) will have a new field added to
  byte TCAAPFLG thus:
  
  .... 1... TCATSUSP      DFHAPIN suspend
  
  
  Dsect SIT ( System Initialization Table ) will have a new field
  added to byte SITMISC thus:
  
  ..1. .... SITICARI      AUTORESETTIME=IMMEDIATE
