Issue
What is the difference between the TimeOfLog and TimeStamp columns in an Alarm or AccessEvent listview?
Environment
Alarm or AccessEvent listview
Cause
One reason as to why there could be a difference between the two is that the controller did not have communications with the workstation that is logging the events so it buffered the events until such time as it could send them. Another reason is that this is a remote site (RAS) setup and the controller was buffering the events until the controller or workstation requested an update of the alarms and events.
Resolution
Generally these two timestamps should be close to the same value. The difference between these 2 columns is that the TimeStamp column is actually when the Alarm or Access Event happened, the TimeOfLog column is when these events were logged into the database.
