The preset default value “”, which indicates that the credential cannot expire, is the only valid setting for this property.
The DesiredCredentialTime property is not currently supported for any mechanism, but is reserved for future use.
Vantage mechanisms do not currently support a time limit on the user credentials. The system ignores any edits to the value of this property.
