Long time press and random time values - unity3d

Question

I want to trigger an event after tot seconds of long press on a touch screen.
I'm trying to achieve this goal with the following code.
The problem is that the time that has passed is, in some way, random.
private float timePressed = 0.0f;
private float timeLastPress = 0.0f;
public float timeDelayThreshold = 2.0f;
void Update() {
checkForLongPress(timeDelayThreshold);
}
void checkForLongPress(float tim) {
for (int i = 0; i < Input.touchCount; i++)
{
if (Input.GetTouch(0).phase == TouchPhase.Began)
{
// If the user puts her finger on screen...
Debug.Log("Touch start");
timePressed = Time.time - timeLastPress;
}
if (Input.GetTouch(0).phase == TouchPhase.Ended)
{
// If the user raises her finger from screen
timeLastPress = Time.time;
Debug.Log("Releasing Touch");
Debug.Log("Time passed --> " + timePressed);
if (timePressed > tim)
{
Debug.Log("Closing APP");
// Is the time pressed greater than our time delay threshold?
Application.Quit();
}
}
}
}
The Fact is that this condition "(timePressed > tim)" is never true and i do not understand why.

Time.time returns The time at the beginning of this frame (Read Only). This is the time in seconds since the start of the game..
Fixed pseudo code:
if (Input.GetTouch(i).phase == TouchPhase.Began)
{
_timePressed = Time.time;
return;
}
if (Input.GetTouch(i).phase == TouchPhase.Ended)
{
var deltaTime = Time.time - _timePressed;
if (deltaTime > _maxTimeTreshold)
{
Application.Quit();
}
}
