Ok, I figured it out.

When I create the objects, the things that I'm passing in are simple
scalars, so the code in _deflated_column doesn't monkey with them and
they're written to the database as is (as simple integers in this

Once I have a real object in hand and I *change* the value, Class::DBI
inflates the column for me so that it's value is a reference to an
object.  When *that* gets passed down into _deflated_columns it sees
it as an object and tries to deflate it.  Since I didn't include a
deflate sub {}, I've been ending up with the default stringification.

Adding a deflate sub that's just sub {$_[0]->epoch} makes everything
