The purpose of this function is to find all entries on the WORKITEM table which have timer triggers whose deadline has passed so that the triggers can be fired.
Note that a timer trigger is NOT fired the second that the deadline is passed as it requires a running process to detect that event and take whatever action is necessary.
This script is not run through a web browser, it is run in the background through the command line via a timer process such as cron. This can be scheduled to run as many times each day as is deemed necessary.
