This new logic script is meant to be a count-up / count-down timer. You could use it, for instance, to track each player's "health" in a game, counting hits down to zero (death). Or to track how many people have visited some part of your experience (count up) since the scene started up. Or show a current count of people in your scene by counting up and down as people arrive and leave. There are many possibilities.
This is the very first Reflex script to feature math. There will be more.
