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
https://www.ibm.com/support/knowledgecenter/#!/SSFKSJ_8.0.0/com.ibm.mq.dev.doc/q119200_.htm
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.
