Hello, 

My beer/coffee/perocet levels are too low to want to comment broadly on
this, so I'll just make one comment ...

I'm not sure why the later would be any more prone to mistakes than
the former. Surely the conversion of

  <time-as-stored-in-whatever-arcane-format-files-my-model-spits-out>

    to

  '2434567 days since -4713-01-01T00:00:00Z'

would be handled by a software library, just as would the conversion
of

  <time-as-stored-in-whatever-arcane-format-files-my-model-spits-out>

    to 

  '1952-08-15T00:00:00Z'

and its fair to assume, I think, that such libraries will do the right
thing.

All the best,

David
