This read-write value sets the upper time bound for filtering command-log entries: only events with an EventTime less than this value are included in a read or delete operation, with a null value meaning no end-time filter is applied. Admins set it together with commandLogStartTimeFilter to bound a log export or purge to a specific time window. For example, setting commandLogEndTimeFilter alongside a start-time filter restricts the operation to commands logged within that exact window.
