Why does strtotime('a') return a time?
<p>I am looping through a CSV file in PHP 5.3 and checking for dates.  I have been using strtotime(), and it has worked well, except for one field I have that contains either a 1 or 2 char code.  </p>

<p>strtotime() on any single char code seems to act like I am asking for now(), but if the code is 2 chars, it fails, as I would expect it to.</p>

<p>What am I not understanding about the way strtotime() works?</p>
