This changelog doesn't really explain what the change is supposed to
be doing or why which makes it very hard to review, and the code is far
from obvious. I can't really tie much of the change to the words here.

If this validation is needed it should be in the regulator core.

I *think* this is all open coding the core's DT parsing support.
