So currently we choose to use either the field_accessors or fields partial based on if we determine a type to be a class or a struct. Unfortunately this doesnt always line up. git_time has standard fields on it, that can be set, but are treated as access functions only, because it is determined to be a "class".

I'm starting to think that maybe the whole class/struct thing needs to fade together, but short term, we should at least try to get this fixed. I can take a look at this, since it's kind of making some date-time stuff tricky.
