The timestamp to dates problem for PHP >= 5.1
<p>I may say I'm not a PHP programmer. I've been reading at <a href="http://php.net/manual/en/function.date.php" rel="nofollow">http://php.net/manual/en/function.date.php</a> that:</p>

<blockquote>
  <p>The valid range of a timestamp is
  typically from Fri, 13 Dec 1901
  20:45:54 GMT to Tue, 19 Jan 2038
  03:14:07 GMT. (These are the dates
  that correspond to the minimum and
  maximum values for a 32-bit signed
  integer). However, before PHP 5.1.0
  this range was limited from 01-01-1970
  to 19-01-2038 on some systems (e.g.
  Windows).</p>

<p>I've database full of 1070-based-timestamps. How can I recover them with PHP >= 5.1?</p>
