I have the following code... It seems to return an inaccurate calculation. I'm relatively new to Objective C and cannot figure out what is going wrong. By my calculations the difference (in seconds) for 4 days should be somewhere closer to 346,600 than 1917995008. Am I wrong?

Code:

NSDictionary *fsAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:uniquePath error:nil];
NSDate *fileDate = [fsAttributes objectForKey:NSFileModificationDate];

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"MMMM dd, yyyy h:mm a"];
NSString *dateString = [format stringFromDate:fileDate];

NSDate *now = [[NSDate alloc] init];
NSString *nowString = [format stringFromDate:now];

NSLog(@"Now: %@", nowString);
NSLog(@"Cache File Date: %@", dateString);
NSLog(@"Cache File Age in Seconds: %d", [now timeIntervalSinceDate:fileDate]);
[format release];


This is what gets logged to the console:
