Hi everyone,

I try to get the last modification date of a file:

NSFileManager *fm = [[NSFileManager alloc] init];
NSError *err;
NSDate *lastModif = [[fm attributesOfItemAtPath:filename error:&err] objectForKey:NSFileModificationDate];//filename is ok ;-)
if(err == nil) {
    [lastModif retain];
    //I can put a NSLog of lastModif here, it works !!
    NSTimeInterval lastModifDiff = [lastModif timeIntervalSinceNow];//crash here
}

I don't understand why the NSDate seems to be released, why the retain does not retain it.

Thank you if you have any idea...
