Currently, the datetime unittest coverage is 95%. Some of the 0 cases suggest 
low hanging fruit.

Despite what I just said, datetime has one of the highest unittest coverages of 
any phobos module. Pretty much all of the phobos module unittest coverage 
testing indicates more work is needed.

Minor perf improvement: the order of the tests in yearIsLeapYear() should be 
reversed, especially since signed divide is a very slow operation, and it is 
called 20 million times by the unittests!!!
