It's in an autorelease pool?

Lets say I have a simple method...

method.h ...

@interface Method : NSObject {
     NSDate        *date;
}
-(id)init;
-(void)setNewDate:(NSDate *)date;

@end

method.m ...

@implementation Method

//Init Methods
-(id)init
{
self = [super init];
date = [[NSDate dateWithTimeIntervalSinceReferenceDate:0] retain]; <<< see below for question
return self;
}
-(void)setNewDate:(NSDate *)newDate
{
[NewDate retain];
[date release];
date = newDate;
}
@end



Question:
The line ....
date = [[NSDate dateWithTimeIntervalSinceReferenceDate:0] retain];
date must be retained, yet, retaining it, sets the retain count to 2.


This does not make sense to me. Why should the retain count have to be 2?
As only one object references date.
