java - Comparing two dates using Joda time

I want to compare two dates, however I'm running into trouble. 1 date is created from a java.util.date object and the other is manually crafted. The following code is an example:

Date ds = new Date();
DateTime d = new DateTime(ds);

DateTime e = new DateTime(2012,12,07, 0, 0);
System.out.println(d.isEqual(e));

However the test turns out false. I am guessing that it is because of the time. How can I check if these two dates are equal to each other (I mean the Year, month, date are identical)?

System.out.println(d.toDateMidnight().isEqual(e.toDateMidnight()));

or

System.out.println(d.withTimeAtStartOfDay().isEqual(e.withTimeAtStartOfDay()));
