Time representations are important in non-calendaring contexts too. As a
generalised framework for the CPAN, I'm sure some people who don't care
about reefknot will want to use it. ;-)

Attosecond precision is meaningless in real applications, but the SS.NN
syntax doesn't penalise the common case. Anything which doesn't need
sub-second precision can just ignore it.

$self->{FOO} might mean different things to Date::Foo and Date::Bar, and
re-blessing references between classes doesn't call the constructor for
the second class. It's not worth the trouble to try to get everyone to
use unique keys (or, indeed, a hash-based object representation).
