The event timer is often used for countdown purposes. However, sometimes you would like to have a bit more control over it, such as being able to pause and resume the timer, increase or decrease the seconds, minutes, or even hours on the timer. Don’t want a countdown timer? Why not have it count upwards instead? Experienced Lunatic Mode coders will be able to add in their own plugin commands, too!
