This has nothing to do with the language specification. Please choose categories accurately.

I can not reproduce this with PHP 5.5.21:

derick@whisky:~ $ cat /tmp/68871.php
<?php
date_default_timezone_set('UTC');
$time = time();
$time2 = strftime('%s', $time);
var_dump( $time, $time2 );
?>

derick@whisky:~ $ php -ddate.timezone=Asia/Taipei /tmp/68871.php 
int(1421841507)
string(10) "1421841507"

What do you see different here?
