I believe you're referring to the "FirstMessageTimestamp" attribute of the QueueControl MBean. There is no such "FirstTimestamp" attribute on any management bean.
The "FirstMessageTimestamp" is the timestamp (in milliseconds) of the first message on the queue. If there is no message on the queue then the value will be empty.
