title: Drupal 7 - How to insert unix timestamp into database
body: <p>Drupal newbie question.  I'm trying to insert the current date/time into a SQL database as a unix timestamp.  It's working in that I'm not getting an error but it just inserts the same value every time (2147483647).  I'm working on a localhost (if that makes a difference) and have tried the following, all to no avail:  </p>
  
  <pre><code>format_date(strtotime('now'), 'custom', 'YYYY-MM-DD 00:00:00'); 
  
  format_date(time(), 'custom', 'YYYY-MM-DD HH:MM:SS'); 
  
  format_date(mktime(), 'custom', 'YYYY-MM-DD HH:MM:SS');
  </code></pre>
