<?php
// format got from a PostgreSQL datetime column type
$date = '2001-10-22 21:19:58+02';
$stamp = strtotime($date);
$conv = date('d/m/Y H:i:s', $stamp);
echo "$date\n$conv\n";
?>

Output:
2001-10-22 21:19:58+02
22/10/2001 23:17:58

It is adding 2 hours and substracting 2 minutes in all the cases (tested with more $date values).
