title: why is strtotime("now -1hours") a different format (am/pm) than strtotime("now +1hours") (24h)?
body: <p>I'm doing an INSERT into my db with these PHP variables: </p>
  
  <pre><code>$startdate1=strtotime("now -1hours");
  $enddate1=strtotime("now +1hours");
  $startdate= date("Y-m-d h:i:s", $startdate1);
  $enddate= date("Y-m-d h:i:s", $enddate1);
  </code></pre>
  
  <p>Now, <code>$startdate</code> formats in 24h format. For example, right now it's 13:58 where I live and the db entry correctly is <code>2016-04-11 12:58:37</code></p>
  
  <p>But <code>$enddate</code> seems to format in AM/PM! Accordingly, right now it's 13:58 and the db entry is <code>2016-04-11 02:58:37</code>.</p>
  
  <p>Does someone know why they get formatted differently? I need both in 24h format, so <code>$enddate</code> should be <code>2016-04-11 14:58:37</code> instead of <code>2016-04-11 02:58:37</code>.</p>
