IJ09088: INTRODUCING A NEW PROPERTY FOR TURKEY TIMEZONE FOR PRODUCTS NOT IDENTIFYING TRT

APAR status

• Closed as program error.

Error description

• Error Message: IBM JDK displays TRT timezone for Turkey, though
  the same has not been accepted by IANA and Oracle JDK which
  still display EET as the timezone.
  This causes issue for products who want historical data (prior
  to the Turkey TZ change in 2016).
  Existing display name:
  Turkey time (TRT)
  Correct display name:
  Should be Eastern European Time (EET) or Turkey time (TRT)
  depending on the product
  .
  Stack Trace: N/A
  .
  

Local fix

Problem summary

• IBM JDK has changed the short name of Turkey timezone from
  EET/EEST to TRT as part of constant offset of GMT+0300. However,
  openJDK decided to stay back the time zone short name as EET and
  only change the time offset. This can result in compatibility
  issues when application on IBM JDK communicate to an application
  on other JDK implementation.
  

Problem conclusion

• JDK has been updated to provide a fallback mechanism  to switch
  from TRT to EET for Turkey timezone with a property. By default
  the property is disabled and IBM JDK uses TRT as timezone short
  name. If application requires EET as timezone short name, use
  property ibm.legacyTimezone=true.
