If possible, upgrade to a version listed in the Fixed In field below. If you are unable to upgrade, load the attached UI script named sys_ui_script_date_time_positiioning_workaround.xml as a workaround to fix the issue. Be sure to remove this script before you next upgrade; leaving the script in place will cause serious issues.
