Try changing the %d to a %ld ? I've had problems with that before...

OK, I set up a new project and copied the relevant lines. The whole project looks like this:

@implementation Controller

- (id) init {
if (self = [super init]) {
double interval = 1.0;
timer = [[NSTimer scheduledTimerWithTimeInterval:interval target:self selector:@selector(timerAction:) userInfo:nil repeats:YES] retain];
}
return self;
}

- (void) timerAction: (id) sender {
NSLog(@"- interval as returned: %f, interval as int: %d",[timer timeInterval], (int)[timer timeInterval]);
}

@end

Maybe there is something wrong with the code, but I dont see it. And as before, this code results in the following being written to the console on my G4:

## Component Manager: attempting to find symbols in a component alias of type (regR/carP/x!bt)
2003-01-10 13:58:04.390 TimerTest[834] - interval as returned: 1.000000, interval as int: 1
2003-01-10 13:58:05.389 TimerTest[834] - interval as returned: 1.000000, interval as int: 1
2003-01-10 13:58:06.389 TimerTest[834] - interval as returned: 1.000000, interval as int: 1

On the other hand on the G3 iBook:

2003-01-10 14:00:37.286 TimerTest[413] - interval as returned: 1.000000, interval as int: 0
2003-01-10 14:00:38.284 TimerTest[413] - interval as returned: 1.000000, interval as int: 0
2003-01-10 14:00:39.283 TimerTest[413] - interval as returned: 1.000000, interval as int: 0

I am not making this up, and you are more than welcome to downlad the project at: http://www.sb-software.de/TimerTest.tgz


I still think this is extremly strange and would appreciate any kind of explaination.

I made a simple countdown app on my G4,
using a simple NSTimer (countDown), firing every 1.0 seconds. However:
double interval = [countDown timeInterval];
NSLog(@"time interval: %f, rounded: %d",interval,(int)interval);
the above code gives, correctly on my G4:
2003-01-09 16:55:56.750 CountDownApp[697] time interval: 1.000000,
rounded: 1
But when running the app on an iMac G3 or my iBook (G3 obviously), it
results in:
2003-01-09 16:58:20.832 CountDownApp[697] time interval: 1.000000,
rounded: 0

I cannot reproduce your problem on my iBook. I create a timer with:
double interval = 1.0;
NSTimer *timer = [NSTimer
scheduledTimerWithTimeInterval: interval
target: self
selector: @selector(timeGentlemen:)
userInfo: nil
repeats: YES];
and then the method:
+ (void)timeGentlemen:(NSTimer *)theTimer
{
NSLog(@"It is now %@", [[NSDate date] description]);
double value = [theTimer timeInterval];
NSLog(@"%f %d", value, (int)value);
}
prints out:
1.000000 1
every time.
