Severity: 4-Minor


When the BIG-IP system is configured to produce log files in an ISO date format, the GUI page System :: Logins renders the string 'Invalid Date' for log entries.


The system reports the string 'Invalid Date' for log entries. Cannot determine dates of log entries.


-- The DB variable 'iso-date' is set to enabled. -- Login records are reviewed.


There is no workaround at this time.
