@Neelz saying right If in DB you are saving only hours & minute value then it will be depends on you which date you are using to get the formatted date.I did the same which @Neelz said but in different way.Below I shown the code by considering the today’s date to get the date time as you need

   //get the today's date
    NSDate* date = [NSDate date];
    //Create the dateformatter object
    NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];
    [formatter setLocale:[[NSLocale alloc]initWithLocaleIdentifier:@"en_US"]];
    //Set the required date format to get the todays date
    [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
    [formatter setDateFormat:@"yyyy-MM-dd"];
    [formatter setTimeZone:[NSTimeZone systemTimeZone]];
    NSString* cCurrentDateStamp = [formatter stringFromDate:date];
    NSLog(@"%@",cCurrentDateStamp);

    //now get the hours & minute you saved in DB.I considered 11:08
    NSString *strYOurTime=@"11:08";

    //create the date time string by appending date & time
    NSString *str=[NSString stringWithFormat:@"%@ %@:00",cCurrentDateStamp,strYOurTime];

     //set the formatter
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
    NSDate *FinalDateTime=[formatter dateFromString:str];
    NSLog(@"%@",FinalDateTime);

FinalDateTime is the final date which you want.Now to get the number of days between two dates refer following link:
