Property Value

Type: AFTime
Returns the time when the object's configuration was last modified.

Remarks

The object's modify date is only updated by the server when a change to its configuration is successfully checked in. Most template changes do not update the modify date of the object. An update to an attribute value that is not a configuration item (i.e. its IsConfigurationItem is set to ) will also not update the object's modify date.
