# displayAckTime attribute

The displayAckTime attribute specifies whether to show the Acknowledge Time column in the alarm list object. This column shows the time the alarm was acknowledged.

The alarmList graphic object element contains this attribute.

FactoryTalk View equivalent: DisplayAckTime

If you set the listType attribute to Unacknowledged alarms only, the DisplayAckTime column is always empty, because as soon as the alarm is acknowledged, the application removes the alarm message.
