  Fix for bug #19370: DateTime datatype in MySQL has two bugs in it
    - Regardless of the title of the bug the only real bug is that it
      doesn't make sense to have only some invalid parts in a date.
      E.g. a valid day among invalid years or months is totally ambiguous 
      and we should refuse to guess what it means.
  
      To fix it, we add a check that both the year is zero and either day
      or month are zero (year and (day or month)), and if they are then  we
      reject such dates. Doing so should adequately fix the reported problem.
