`PHP Fatal Error: date(): Timezone database is corrupt` on redhat 6.9, nginx, php-fpm

I got an error while calling date() on php-fpm.

I know php-fpm works well with phpinfo() operates.

I have given permission 777 to /usr/share/zoneinfo and /etc/localtime. But still not working.

Here's my source code and environemnt.

# time.php
<?php
    echo date('r');
?>
