The plugin shared.make_timestamp.php will fail if passed a Unix epoch seconds number in 1970:

Example:
Code:

<?

echo date("r",smarty_make_timestamp(mktime(5,0,0,1,1,1970))); # shows a date in 2007
echo date("r",smarty_make_timestamp(mktime(5,0,0,1,1,1971))); # shows correct date

function smarty_make_timestamp($string)
{
    if(empty($string)) {
        $string = "now";
    }
    $time = strtotime($string);
    if (is_numeric($time) && $time != -1)
        return $time;

    // is mysql timestamp format of YYYYMMDDHHMMSS?
    if (is_numeric($string) && strlen($string) == 14) {
        $time = mktime(substr($string,8,2),substr($string,10,2),substr($string,12,2),
               substr($string,4,2),substr($string,6,2),substr($string,0,4));

        return $time;
    }

    // couldn't recognize it, try to return a time
    $time = (int) $string;
    if ($time > 0)
      return $time;
   else
      return time();
}

?>

make_timestamp doesn't work reliable for very low timestamps because
php's strtotime doesn't work reliable with short timestamps. at least that's the result of this thread:

http://www.phpinsider.com/smarty-forum/viewtopic.php?t=223#1334

your first example ( mktime(5,0,0,1,1,1970) ) leads to timestamp 14400.
my strtotime parses year=1 month=44 day=0 and flattens that to year=4 month=7 day=31 so on my machine it becomes "Sat, 31 Jul 2004".

if you don't need the mysql-timestamp magic of date-format but need a reliable date-format for low timestamps it's easy to write your own little timestamp_format-modifer with php's strftime()
