A read-only Date property indicating the last time the Server was disconnected during the current program execution.
The object placeholder is an object expression that evaluates to a Server object.
The returned value is a DATE.
If the server has never been disconnected during the current program's execution, the DATE value is set to 0. This value, once set, is not cleared when the server is reconnected. It remains valid until the new connection is closed at which time it is updated to the new disconnection time.
