Store time from NSTimer for next view (HELP!)

Programmer Question

Hey,

I'm becomming desperate. I've got a NSTimer in my second ViewController.

-(IBAction)start {
    myticker = [NSTimer scheduledTimerWithTimeInterval:0.01 
                                                target:self 
                                              selector:@selector(showActivity) 
                                              userInfo:nil 
                                               repeats:YES];
}

-(IBAction)stop {
    [myticker invalidate];
}

-(void)showActivity {
float currentTime = [time.text floatValue];
newTime = currentTime + 0.01;
time.text = [NSString stringWithFormat:@"%.2f", newTime];        
}

newTime ist an instance variable (float) and time is the label where the time is shown.

Before calling the third ViewController, I stored the time this:

-(IBAction)right {

[self stop];

ThirdViewController *screen = [[ThirdViewController alloc] initWithNibName:nil bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
screen.timelabel.text = [NSString stringWithFormat: @"%.2f", newTime];
[self presentModalViewController:screen animated:YES];
[screen release];
}

I stopped the timer and gave the time to the instance variable timelabel (UILabel).
In the third ViewController I created the same NSTimer with the same methods.
But when I open the third View Controller the timer starts from 0 again.

What's wrong about my code?
