APAR status

• Closed as program error.

Error description

• In testing it has been found that setting hrSystemDate and then
  getting hrSystemDate can sometimes return a time that is 1 hour
  different to what was set. This is particularly apparent on
  Linux if the timezone is set to China and the year < 2000.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of hostres on Unix/Linux.

  PROBLEM DESCRIPTION:
  Setting hrSystemDate can be off by one hour on Unix/Linux
  ****************************************************************
  RECOMMENDATION:
  Upgrade to Fix Pack 9 for SSM 4.0.

Problem conclusion

• Found a daylight saving (DST) field was uninitialized resulting
  in a system time which was sometimes 1 hour off. Fixed the
  uninitialized DST field and merged all Unix/Linux code for
  setting hrSystemDate so it will now be consistent on all
  platforms.
