    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"hh:mm dd/MMM"];
    NSDate *dateFromString = [[NSDate alloc] init];

Try this

    NSString *dateString = [dateFormat stringFromDate:today];
    NSLog(@"date: %@", dateString);
    [dateFormat release];
