Using Joda, How do I determine if a given date is between time x and a time 3 hours earlier than x?

What is the simplest way to use Joda time and ge开发者_Python百科t something like the following behavior:

public boolean check( DateTime checkTime )
{
    DateTime someTime = new DateTime(); //set to "now" for sake of example
    return checkTime.isBefore( someTime ) && checkTime.notMoreThanThreeHoursBefore( someTime );
}

So if someTime is set to 15:00 and checkTime is set to 12:15 it should return true.

If someTime is set to 15:00 and checkTime is set to 11:45 it should return false because checkTime is more than 3 hours before someTime.

If someTime is set to 15:00 and checkTime is set to 15:15 it should return false because checkTime is after someTime.

After some playing around, I found this which reads nicely:

return new Interval( someTime.minusHours( 3 ), someTime ).contains( checkTime );

Easy:

DateTime someTime = new DateTime();
DateTime earliest = someTime.minusHours(3);

if (earliest.compareTo(checkTime) <= 0 && checkTime.compareTo(someTime) < 0)

I've used compareTo as there's no isBeforeOrEqual or isAfterOrEqual - but you can use compareTo for any relation.

I suspect it was just minusHours that you were after though :)
