Compare Date objects with different levels of precision

I have a JUnit test that fails because the milliseconds are different. In this case I don't care about the milliseconds. How can I change the precision of the assert to ignore milliseconds (or any precision I would like it set to)?

Example of a failing assert that I would like to pass:

Date dateOne = new Date();
Date dateTwo = new Date();
assertEquals(dateOne, dateTwo);


Use a DateFormat object with a format that shows only the parts you want to match and do an assertEquals() on the resulting Strings. You can also easily wrap that in your own assertDatesAlmostEqual() method.
