UPDATE: Resolved.. See post 4 at the link below for the working parent function to return setting/state variables to a child app. I'm sure this could be improved, but it's working for me.
@bravenel and/or anyone else that may be able to offer advise.. I'm super close on resolving the parent/child variable issue but have run into an issue I am not sure how to resolve.

I'm not sure how to detect/cast these to date/datetime.
I'm moving discussion on this particular issue here under a topic of it's own:
