sorry it's confusing. Calculate is not proper I think. Let me quote Taro's

  | Time
  |  t1  Producer1 ---> Message1 ---> Queue1
  |  t2  Producer2 ---> Message2 ---> Queue1
  |  t3  Producer1 ---> Message3 ---> Queue1
  |  t4  Producer2 ---> Message4 ---> Queue1
  | 
  | Where Time "tn" (n is integer) means the one when Queue1 receives a message from a producer
  | (the time relies on the clock on machine of Queue1).

  | Then, Queue1 has Message1, Message2, Message3 and Message4 in order and the consumer consumes the messages in this order.
