See if you would like to enhance it further. As a "security measure" I included a check that the interval must be greater than 500 milliseconds. This is appropriate for the public demo, but occasionally for performance testing it is useful to set the interval to 100 milliseconds (perhaps this should be the lower bound).

The clock tick interval can now be changed via the administrative page that is included with the app (auctionControl.jspx). In addition, setTickInterval and getTickInterval are now available so that you can use a managed-property of the bean configuration to set the starting tick interval value. Resolving as fixed.

Changing it to a value below 1000 ms should still show the clock ticking every second. On the back-end, it will be attempting to do 10 pushes per second but since the time only really changes once per second, the other pushes should not result in any updates. Setting the interval about 1 second should slow the ticks depending on the interval. If the clocks stop ticking altogether when the interval is changed, then it's a bug.
