Yes, that's true, the failure will only be apparent when a DST
transition is sufficiently close by. However, the problem with the
current behavior is that the failure isn't obvious even then ---
you might not notice the data inconsistency until much later when
it's not possible to sort things out.
The current code behavior seems to me to be on par with, for example,
trying to intuit MM-DD versus DD-MM field orders. We used to try to
do that, too, and gave it up as a bad idea.
