Issue
Most recent access events do not appear in door's events tab.
Environment
CyberStation
CX9680
ACX5740/20
CX9702
CX9900
ACX7xx
Cause
Events recorded with invalid time stamp in the future (i.e year 2089).
At some point and for unknown reasons the controller was using a time stamp with the year set to 2089, these events show up first in the door events tab and fill it up.
Resolution
From a list view of access events delete all events that have a time stamp in the future.
