Maven – mvn command is not recognized as an internal or external command

Maven 3.0.3 and later doesn't need the M2_HOME variable. The following environment variable changes are sufficient to run Maven from the command-line:

1. Setting JAVA_HOME to the Java jdk directory (eg. C:\Program Files\Java\jdk1.6.0_29)
2. Setting PATH to include the Maven bin directory.

I do recommend using an NSDate object to store the time the store closes instead of using your own custom integer format. It's unfortunate that NSDate represents both date and time of date.

In any case, you can check NSDateComponents. You can have a utilities method like:

int minutesSinceMidnight:(NSDate *)date
{
    NSCalendar *gregorian = [[NSCalendar alloc]
        initWithCalendarIdentifier:NSGregorianCalendar];
    unsigned unitFlags =  NSHourCalendarUnit | NSMinuteCalendarUnit;
    NSDateComponents *components = [gregorian components:unitFlags fromDate:date];

    return 60 * [components hour] + [components minute];    
}
