I'm not sure of the final consensus on what exactly the behavior should be.

The ranges are only in there as an earlier catch of an invalid date - they
no longer are part of the earlier logic which allowed a "pass-through."
They should be removeable with no effect. I'll write up a new patch.
Does this logic seem correct?

if (US) {
  YYYY-MM-DD
  MM-DD-YYYY
}
else {
  YYYY-MM-DD
  DD-MM-YYYY
}

In other words, the US is backwards from the rest of the world.
(as far as MM-DD-YYYY)

Thanks,
