Time Zones.

Unity Engine

Hi, are there multiple time zones? like a public time zone and a personal time zone? what i want is my time bomb (i got the script from someone else!) to do a countdown on a fixed timescale so when i spawn a second bomb it isn’t something like: -5.9898864. if anyone knows what i should change in the script. the script is shown below.

var detonationTime = 10.0; 

function Update() { 
   GetComponent(TextMesh).text = "" + (detonationTime - Time.time);
}

if possible i’d like to be able to block the veiw of the 3d text so it is not visible through the wall. Help would be apreciated.

var duration : float = 10;
private var detonationTime : float;

function Start() {
detonationTime = Time.time + duration;
}

function Update() {
   GetComponent(TextMesh).text = "" + (detonationTime - Time.time); 
}
