Implements delay using a special exchange behaviour {{"x-delayed-message"}}.
Application specifies messages delayed by adding a {{x-delay}} header which
contains the number of milliseconds the message should be delayed by.
http://docs.jboss.org/hornetq/2.2.5.Final/user-manual/en/html_single/index.html#d0e5312
Application sets message header {{_HQ_SCHED_DELIVERY}} containing an absolute
time. (Wonder if there is some compensation for clock skew?).
http://activemq.apache.org/delay-and-schedule-message-delivery.html
Application sets message header {{AMQ_SCHEDULED_DELAY}} containing contains the
number of milliseconds the message should be delayed by.
ActiveMQ also implements other value-add features in this same space - repeat
periods, repetitions etc

Uses the JMS 2.0 API {{JMSProducer.setDeliveryDelay(long deliveryDelay)}}

> Key: QPID-7255
> URL: https://issues.apache.org/jira/browse/QPID-7255
> Project: Qpid
> Issue Type: New Feature
> Components: Java Broker
> Reporter: Keith Wall
>
> Some enterprise messaging systems provide a delayed delivery feature whereby
> a publisher can provide a delivery time when sending the message, with the
> Broker taking care of not making the message available to consumers until
> that time is reached. The Java Broker should provide the same feature.
> In the Java space, JMS 2.0 has standardised this feature, however there is
> no reason why the feature could not be made available to older JMS 1.1
> clients using a Qpid specific header.
