EnqueueTime (which really should have been called EnqueueDuration) = TimeOfDequeue - TimeOfEnqueue, which correspond to the two events I described in my first response. TimeOfDequeue is when the message is acked by the consumer, which depending on how you're configured might be before the consumer processes the message (auto-ack mode) or after it processes the message (one of several manual ack modes).
