IJ41613: TIMEZONE CANNOT BE CHANGED FROM UI AND SYSTEM TIME SETTINGS UI TAB MIGHT FAIL TO LOAD

APAR status

• Closed as program error.

Error description

• In QRadar 7.5.0 Update Package 2, When the timezone is changed
  in the System Time Settings tab from the System and License
  Management window in the UI, the change is not saved. After the
  attempted change, the timezone_id becomes invalid and as a
  result, the System Time Setting tab fails to load. Errors
  similar to the following appear in /var/log/qradar.log:
