Thanks Naoto, Roger for the review!
For Naoto's concern about the equals method using EonAndYear and
FractionalSecond, I did cut corners using the all int getXXX method. The
rational was: it fulfills the equals-hashcode contract just fine, is
consistent with the existing implementation, and concise. This API was
introduced since 1.5, but I have yet to see any usage of EonAndYear, and
very rarely FractionalSecond. The chances collisions occur due to these
differences are very low.
But I understand your concern. To be precise or exact as equals(), we
would need to call getFractionalSecond and EonAndYear. Here's what that
would look like:

To me, I like version 1 for the reasons above:

What would you think?

Hi Joe,
For the consistency with equals(), just wondering if the sub-second
element should be obtained with getFractionalSecond() instead of
getMillisecond(), as the equals() subsequently calls it in
internalCompare() method. Also should it call getEonAndYear()
appropriately for the year?
