@macumber Ah, I see. That is a good idea.

I didn't add the time entries to the enum because of the year issue. Initially, I wanted to take the time entries and role them up into a DateTime object and not store the parts. I backed off of that when it became clear that it might cause issues. I think I understand OpenStudio's expectations a little better now, so I could probably try it now but I think I'd rather do that as a separate pull request.
