Problems with NSDate - or how to ignore date / timezone?

Well, I refused this. Here's what I'm trying to do: I have sunrise, sunset, and current time in a specific time zone. I want to know if it is day or night, figuring out if the current time is between sunrise and sunset.

Here is what I have:

NSLog(@"%@ - %@ - %@",currTime,sunrise,sunset);

NSDateFormatter *formatter1 = [[NSDateFormatter alloc]init];
NSDateFormatter *formatter2 = [[NSDateFormatter alloc]init];
[formatter1 setDateFormat:@"hh:mm a"];
[formatter2 setDateFormat:@"EEE, dd MMM yyyy h:mm a z"];
NSDate *rise = [formatter1 dateFromString:sunrise];
NSDate *set = [formatter1 dateFromString:sunset];
NSDate *time = [formatter2 dateFromString:currTime];    
[formatter1 release];
[formatter2 release];

unsigned int flags = NSHourCalendarUnit | NSMinuteCalendarUnit;
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components1 = [calendar components:flags fromDate:rise];
NSDateComponents *components2 = [calendar components:flags fromDate:set];
NSDateComponents *components3 = [calendar components:flags fromDate:time];

NSDate *Sunrise = [calendar dateFromComponents:components1];
NSDate *Sunset = [calendar dateFromComponents:components2];
NSDate *Time = [calendar dateFromComponents:components3];

NSLog(@"\nSunrise: %@ \nSunset:%@ \nTime:%@",rise,set,time);
NSLog(@"\nSunrise: %@ \nSunset:%@ \nTime:%@",Sunrise,Sunset,Time);

Here's the first conclusion:

Fri, Jun 10, 2011 4:00 a.m. SAST - 7:46 - 17:41

And here is the second (before doing this only regarding time, not date)

Sunrise: 1969-12-31 22:46:00 +0000

Sunset: 1970-01-01 08:41:00 +0000

Time: 2011-06-10 02:00:00 +0000

And finally, here is the final conclusion (note how the time went wrong?):

Sunrise: 0001-12-31 22:27:01 +0000

Sunset: 0001-01-01 08:22:01 +0000

Time: 0001-01-01 01:41:01 +0000
