By default it should apply to the last five seconds, but it will be 
influenced by the msg_rates_incr argument mentioned here:

So *technically* you shouldn't use this as it is 
undocumented-subject-to-change and also dependent on the backing queue 
implementation.

However, in practice the backing_queue_status hasn't changed since 2.0.0 
and nobody ever changes the backing queue implementation, so you should 
be good.
