Local notifications are not coming on the datetime I want - iphone

Question

I'm working with local notification. I got the notifications working. But I'm struggling with setting the correct date.
Let me first sketch the situation. I am making a festival app. This festival is on the 28-29-30 JUNE. Every artist object has an art_day. This can be 1 - 2 or 3.
1 --> 28 JUNE
2 --> 29 JUNE
3 --> 30 JUNE
I want a local notification 15 min before the start time of the artist. So this is how I'm making my fireDate of the notification.
-(NSDate *)getDateForArtist:(Artists *)artist{
int day = [artist.art_day intValue];
int timeStart = [artist.art_timestart intValue];
NSString *timeStart2 = [self getTimeStamp:artist.art_timestart];
int hours = [[timeStart2 substringWithRange:NSMakeRange(0,2)]intValue];
int minutes = [[timeStart2 substringWithRange:NSMakeRange(2,2)]intValue];
//in my db timeStart looks like 1530 --> 15h30 (I know bad db structure!!!)
int day2;
if(day == 1){
NSLog(#"day is 28");
day2 = 28;
}else if (day == 2){
NSLog(#"day is 29");
day2 = 29;
}else{
NSLog(#"day is 30");
day2 = 30;
}
NSDateComponents *comps = [[NSDateComponents alloc] init];
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:#"GMT"];
[comps setTimeZone:timeZone];
[comps setDay:day2];
[comps setMonth:06];
[comps setYear:2013];
[comps setHour:hours];
[comps setMinute:minutes];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [gregorian dateFromComponents:comps];
NSLog(#"date is %#",date);
NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
[offsetComponents setMinute:-15];
NSDate *date2 = [gregorian dateByAddingComponents:offsetComponents toDate:date options:0];
NSLog(#"date -15 min %#", date2);
return date2;
}
This is how I create my notification
UIApplication* app = [UIApplication sharedApplication];
UILocalNotification* notifyAlarm = [[UILocalNotification alloc]
init];
if (notifyAlarm)
{
NSDate *datePush = [self getDateForArtist:artist];
NSLog(#"artist plays on: %# on hour %#",artist.art_day,artist.art_timestart);
NSLog(#"Push notification should send on: %#",datePush);
notifyAlarm.fireDate = datePush;
NSDictionary *dicNotification = [[NSDictionary alloc]initWithObjectsAndKeys:artist.art_id,#"pushKey", nil];
notifyAlarm.userInfo = dicNotification;
notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
notifyAlarm.repeatInterval = 0;
notifyAlarm.soundName = #"Glass.aiff";
notifyAlarm.alertBody = [NSString stringWithFormat:#"%# starts in 15 minutes",artist.art_name];
[app scheduleLocalNotification:notifyAlarm];
NSLog(#"Added");
}
But for some reason I don't get any push notification. Or I think that the date is not correct.
This is what I get from my logs
2013-06-29 15:37:17.801 genkonstage[14120:907] artist plays on day: 2 on hour 2020
2013-06-29 15:37:17.803 genkonstage[14120:907] Push notification should send on: 2013-06-29 20:05:00 +0000
Can anybody help me with this?
