What about the fact that days are not actually intervals of 24*60*60
seconds (as I'm sure you know)?  Most applications don't care, but
it's crucial to give correct and unsurprising results.

I'm worried that the complexity to deal with leap seconds will end up
being just as complicated as the complexity to deal with more general
TimeDiff's as in the current library, in which case it may be
necessary to bite the bullet and specify the behaviour of TimeDiffs
completely and accurately.
