title: Interpret any date from any string
body: <p>I have various formats of dates, in strings, all in ColumnA.  Here is a small example.</p>
  
  <pre><code>-rw-r--r--   35 30067    10224     &lt;-- 2018-09
  -rw-r--r--   36 30067    10224     &lt;-- 2018-09
  -rw-r--r--   65 30067    10224     &lt;-- 2018-10-24
  </code></pre>
  
  <p>Is there a way I can interpret any date from any given string?</p>
