title: PHP 4 Dates Wrong
body: <p>According to Yahoo, my account is using MySQL 4.1.14, and PHP 4.  Yeah, I know I am a bit behind.  I noticed some funny things started going on with my code a while back, around dates.  But I thought time zone setting did not come into play until PHP 5.</p>
  
  <p>Anyway, I am pulling dates from a database using <code>UNIX_TIMESTAMP</code>, and it gives me a timestamp like 1436745600 for a date 2015-07-13 stored in my database.  This looks correct to me.  But then my code simply does a <code>date('M-j','variable storing that number')</code>, and it gives me 'July-12'.  Why is this?</p>
  
  <p>I know I am PST, and the server is UTC, but on version 4, how would PHP know that?  And even if it did, we are both on the same day for most of a 24 hour cycle.  As I started writing this, we were on the same day, and still the problem occurred.  As I finish, we are on different days, and the result is the same.  Something else going on here?</p>
