This notification variable carries a time tag or sequence identifier that uniquely distinguishes one inadssnmpAlarmMessage from another, since a device could otherwise send multiple alarms whose message text alone doesn't guarantee uniqueness. An admin, or the monitoring application receiving it, uses this value to correlate an acknowledgment or track duplicate or re-sent alarms accurately. For example, an inadssnmpAlarmTime value uniquely tags a specific alarm event so the receiving application can tell it apart from a similar alarm sent minutes later.
