Gordon Sim commented on QPID-3417:
----------------------------------
Are you saying you could set the message timestamp itself dynamically, or just
reconfigure the interval option?
> Support for timestamping messages on arrival at the broker.

> Key: QPID-3417
> URL: https://issues.apache.org/jira/browse/QPID-3417
> Project: Qpid
> Issue Type: New Feature
> Components: C++ Broker
> Affects Versions: 0.13
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Minor
> Fix For: 0.14
>
>
> AMQP 0.10 defines an optional message delivery property of timestamp:
> name: timestamp
> type: datetime
> description: message timestamp
> (optional) The timestamp is set by the broker on arrival of the message.
> I'd like to make use of this timestamp for a proposed debugging feature for
> message groups. See the message groups UI proposal in
> https://issues.apache.org/jira/browse/QPID-3346 for details of its use.
> I think it would more useful to introduce a generic message timestamp
> capability based on the AMQP 0.10 delivery property, rather than integrate
> something limited only to message groups.
> Functional Model:
> The broker would support the configuration of a "timestamp interval". This
> interval would be expressed in millisecond units, and would represent the
> granularity of the message timestamp. The default setting of this interval
> would be zero - which would be interpreted as disabled. When enabled
> (non-zero) the broker would maintain a time-of-day time stamp. This time
> stamp would be updated (resync'ed to the current time-of-day) periodically
> based on the configured "timestamp interval".
> When enabled, each message arriving at the broker will have the "timestamp"
> delivery property set to the current value of the broker's time stamp.
> This feature will need to be able to be turned on and off on demand, without
> restarting the broker. Therefore new QMF methods would be added to the
> broker's QMF object to support run-time configuration:
> method: getMessageTimestamp - returns the configured timestamp value for
> the broker in milliseconds.
> method: setMessageTimestamp - sets the broker's timestamp value (expressed
> in milliseconds).
