Currently an issued trigger is atomic - it is one thing which lasts for as long as you care to configure it.
However, if a trigger is longer than a millislice, GT should break the trigger up into the appropriate number of millislice-sized subtriggers, packing an extra word into the trigger header with the trigger number of the first trigger in this sequence. This makes the event builder's job waaaaay easier.

Have this working, created a GTLongTrigs class which calculates the need for splitting a trigger into smaller chunks, and provides the functionality to loop over that series of smaller triggers, adjusting the time windows appropriately.
Have it working in a test release, doing more testing and looking for a way to clean up the resulting code before releasing it on the world.
