The new timer pluggable is a replacement for the timer gate expansion. The new pluggable should do the following things:

• Have a trigger for 5, 10, and 15 second intervals. This is probably timed relative to the world-clock. An alternative would be to add an action to start, pause, and reset the timer, or split the timer duration into different pluggables entirely.
• Have a model that rotates a hand around it's face. (It is basically a clock, and it would make it possible to tell when the timer will activate the actions.)
