AckTime Not Updating in Event List
When an alarm is acknowledged in the Alarm list the Acktime column is updated to the Acknowledged time, but the same will not be updated in the Event list Acktime column.
Screen Shot has been attached for refrence.
EventTime: available in alarm and event lists
ActiveTime: available in alarm and event lists
AckTime: only available in alarm lists
By enabling "Log Acknowledge" a separate event will be generated at acknowledge, this event can be viewed in event lists, but its the "EventTime" that reflects the actual time the alarm became acknowledged.
