Hey Dan!
I was trying to get your Universal Counting Clock to stop when it hits 00:00:00, but this part threw me:
if (clockTime < 0){
sign = "-";
clockTime = -clockTime;
}else{
sign = "";
}
I tried
if (clockTime < 0) {
clockTime = 0;
but it kept counting. How would you get it to stop counting (either up or down)?
