  The z/OS system time setting may be changed (e.g. for daylight
  savings). Until a RESETTIME command is issued, or SIT parameter
  AUTORESETTIME is used, the changed system time value will not
  be picked up by the CICS system. An application can receive the
  updated time however, by issuing an ASKTIME command to
  refresh its EIB. Until an ASKTIME command is issued, the
  EIBTIME and EIBDATE fields will still reflect the old system
  time. This is because they are populated from CSATODP and
  CSAJYDP at task attach, but updated via a TIME macro when an
  ASKTIME command is issued. A TIME macro picks up the changed
  system time.
  KEYWORDS: MVS clock
  

Problem conclusion

• DFHAPIN has been changed to use a TIME macro to populate EIBTIME
  and EIBDATE with their initial values.
