Also read the following topic or search via forum: Entering/Displaying time values in units other than Milliseconds For remaining runtime, please check this topic: How do you specify the runtime for a timer via an operator panel, or how do you output the remaining runtime?

I would like to have a timer that counts down secunds than minuts and hours. does anyone have a fb. that does this or give me an advice hot to start making one. thank you
